Re: A saner era? Myths about trans kids in schools, courtesy of FOX News

Rosehiptea,

As Holly mentions, the major distinction in types of treatment has to do with whether the diagnosis is made in childhood or later in life. Shrinks are generally respectful enough of their adults patients’ wishes and strongly held convictions, at least on this specific point, not to simple-mindedly force them into efforts to “correct” their transgenderism. Not so for children, where all kinds of nasty behavioral therapy are commonly employed to “cure” them.

Michelle,

I think that when the common features of “diagnostic category” are explicitly described “symptoms,” while the thing itself is explicitly labeled a “disorder” and it is classified as an Axis I Clinical Disorder, it’s a bit odd to suggest that the purpose of the diagnostic category is primarily descriptive, rather than prescriptive. When professional medical practitioners describe a set of behaviors and attitudes in terms that are directly and deliberately taken from the medical study of disease, and describes them as causes for “clinical attention,” it is pretty strongly suggested that there’s something wrong with people who have that “disorder.”

As for the professional ethics in sex-reassignment surgery, it has basically nothing to do with the use of Gender Identity Disorder as a “diagnostic category” in eight year old children, which was the context of the discussion. However, I think that if the sole raison d’etre for this diagnostic category is in order to pander to the prejudices of doctors who can only be persuaded to acknowledge their trans patients’ considered judgment when said patients can get another doctor to sign off on it in the form of an Official Diagnosis certifying that they’re “disordered,” that’s a pretty slender reed to lean on. I’d hope that maybe we can start talking about changes that are important for our lives without first having to get a medical label slapped on it.

As for the study of “outcomes” in children labeled as having GID, cf. Speck’s reply. (Incidentally, last I checked, the DSM-IV TR says that 3/4 of anatomical boys diagnosed with GID end up living as homosexual or bisexual males in their late adolescence; the corresponding figure for anatomical girls diagnosed with GID are said to be unknown.)

But, moreover, I don’t see what the point of bringing this up is in the first place. If 3/4 of GID-diagnosed kids turn out to be gay, then so what? There’s nothing wrong with being gay and there’s nothing wrong with not being gay. There’s nothing wrong with wanting to live as a girl (or boy) when you’re 8 and then deciding you want to live as a gay man (or lesbian) when you’re 16. There’s nothing wrong with wanting to live as a girl (or boy) when you’re 8 and then deciding that you want to continue living as a woman (or man) when you’re 16. There’s nothing wrong with changing the gender you want to live as every four months, if you feel like it. If only a few kids diagnosed GID end up seeking sex-reassignment surgery as adults, what of clinical interest follows from that? It’s certainly not any kind of argument for therapeutic intervention with the kids with strong, persistent cross-gender identification (either potential outcome–remaining trans or not remaining trans–is fine, so what’s the big deal?). Nor is it an argument for trying to get the government to treat 8 year old kids with strong, persistent cross-gender identification as if they had a mental “disability.”

ThickRedGlasses,

“The disturbance causes clinically significant distress or impairment in social, occupational, or other important areas of functioning.” . . . People with Gender Identity Disorder are going to be significantly distressed by being in the wrong body, even if the social stigma goes away.

A significant part of my point is that the criteria having to do with “impairment in social [or] occupational … functioning” are basically bogus. They’re a way of shifting the responsibility for other people’s discrimination and bullying onto the victims of the discrimination and bullying. In reality, insofar as there’s a “disorder” here, it’s because other people have a problem, not because kids labeled as having GID have a problem.

As far as “clinically significant distress” goes, as far as I know, there’s been no positive evidence presented to the effect that the little girl in question feels that way, and I see little reason to assume that she does. Not everybody who wants to live as a member of a gender different from the one they were assigned at birth is especially concerned about the anatomical details of their body, especially not when they are still years away from puberty.

If, on the other hand, she does feel that way, then in any case that’s a separate issue from the accommodations that the school should or shouldn’t make for her. They don’t have much control over her personal feelings about her genitals. The issue at hand is how they will or won’t deal with the questions about her immediate social environment–whether or not teachers and classmates call her by her chosen name, allow her to to come to school dressed as a girl, do or don’t harass her, etc.

From a clinical standpoint, I’d question the utility of creating a gender-specific diagnostic category if the only purpose is to group together people who are (1) trans and (2) depressed or anxious or dysphoric about their bodies. There’s nothing wrong with (1) per se, and there’s already a ton of different diagnostic categories to cover (2), so why come up with a new one just to single out the fact that one subgroup of people who develop (2) are also (1)?

In Defense of Sin: Re-examining the Libertarian Agenda

Jeremy,

I’d like to suggest that the chief reason libertarians and anarchists spend more time assailing government than they spend assailing “mere” crime isn’t so much that the former is institutionalized while the latter isn’t. There are plenty of examples of “mere” crime that’s institutionalized — the Mafia, for starters — that libertarians and anarchists also don’t spend much time fulminating.

What I think is more likely is that libertarians and anarchists spend a lot of time and rhetorical energy on government because over and over again we see that the violence of the State apparatus, no matter how intense and no matter how obviously harmless or helpless its victims, is ideologically mystified, morally excused, and either widely treated as legitimate or else simply rendered invisible, whereas most “mere” crime is not. It doesn’t take a lot of rhetorical energy to convince most people that the Mafia is a band of thugs; most everybody knows that being a band of thugs is their business. Most people don’t know, or don’t consistently realize, that being a band of thugs is the government’s business. Hence the effort to demystify, delegitimize, and get people to come down and look at the actions of governors and their hirelings the way they would look at similar conduct by someone without a badge or a pompous title on letterhead.

Note that when libertarians have been especially concerned with exposing and condemning some form of systemic violence carried out mostly outside of the formal State apparatus — for example the “private” violence of race slavery, or violence against women, or adult domination of children — it is more or less always a parallel system of violence which is, like the State, mystified as being something other than violence, culturally excused, and either explicitly socially accepted or else kept silent and made invisible. Even when (as in the case of, for example, violence against women) there may be various kinds of institutional support or institutional denialism for the violence, but the paradigmatic locus of the violence is in informal actions by one ordinary person against another, carried out in private settings.

I should note that the mystification of State violence also seems to play an important role in arguments that try to undermine the ideal of a consensual society by appealing to the ignorance, folly, or vice of mortal creatures. Of course we are all prone to ignorance, folly, or vice in this vale of tears. But that is precisely the reason to oppose all forms of coercive power. Every government is run by those same imperfect, sinful people that it supposedly exists to straighten out, and certainly the would-be bellowing blowhard lords of the world are no more immune to pride, cruelty, or sharp dealing than ordinary business-people, workers, etc. Quite the opposite. If it’s utopian to imagine perfecting human nature, then certainly you have every reason to centrally concern yourself with institutions, practices, projects, traditions, etc. which take all the ignorance, folly, and vice of those who come out on top of the power-struggle, and then magnify it, concentrate it, regularize it, and insulate it from both criticism and resistance.

That libertarians are simply more consistent in their advocacy of non-agression is no mind-boggingly unique contribution to political discourse; it’s actually just a preference

I don’t know what you mean by this. Clearly one can have a preference for consistency — I’d hope everyone does — but is the phrase “just a preference” supposed to indicate that preferring consistent application of moral principles over inconsistent application of moral principles isn’t backed by some prior logical and/or moral obligation? That it’s just a matter of taste, like preferring milk over lemon in your tea? If so, why do you believe that? If not, then what work is the word “just” doing here?

And I agree with you that, as distasteful as it may be to us, government is comprised of genuine traditions, norms, and social identity.

Again, I’m confused by what you mean here. Are there libertarians or anarchists who deny that government is comprised of genuine traditions, norms, and social identity? (What then do they believe it is comprised of? Idiosyncratic rather than traditional practice?)

The point of anarchistic critique is not that government somehow exists separately from traditions, norms, and social identity, but rather that some traditions, norms, and ways of understanding your social identity are foolish, vicious, or otherwise objectionable, and in particular that the the statist elements of those traditions, norms, and social identity are in need of critique, reform, or revolutionary transformation.

One realization I’ve come to is that I don’t have a problem with force being exerted by society, so long as it is society, and not a particular class of society, executing the force.

And again, I’m confused by what you mean. Force is never exerted “by society.” It is exerted by individual people who live in a society, and, when it’s coordinated, it is always coordinated by an organized faction within that society (whether spontaneously or deliberately ordered), not by the “society” as a whole. This is no less true of “citizen militias” than it is true of professionalized police or government armies. (Barring universal conscription, there will always be a fair number of people who decline to participate. And there will always be a fair number of people — young children, frail people, paralyzed people, etc. — who are incapable of participating. Aside from any limitations through cultural or institutional prejudice, the nature of the practice necessarily limits participation.)

As far as I can see, the only important question here is, not who is or is not exercising the force, but rather how it is being exercised: whether it is being exerted prudently or destructively, and, when it is exerted, whether it is being exerted to vindicate just claims or to violate and suppress just claims. Insofar as there’s a question of “who” involved, it’s only a question of which factions, and which forms of organization, are the most likely to abstain from destructive or aggressive uses of force, and most likely to pursue wise and righteous uses of force. I think the superiority of citizen militias here over unaccountable paramilitary cops or imperial standing armies is obvious, but the reasons for that superiority have little if anything to do with some mythic direction of force by the General Will. It just has to do with what we, each of us individually, in our ordinary lives, are prone to do under different circumstances, when we are dependent on others for our safety, or when we have unaccountable power over others, or when we are able to defend ourselves, or when we are working cooperatively with our neighbors, etc. etc. etc.

John,

The most unfortunate thing about “anarchism” may be the name, which may lead one to believe anarchists are against all gov’t, when really (as I understand it) they are perfectly willing to cooperate with their neighbors for the common good, a good that must inevitably, at times, impinge upon their personal good.

But, John, the reason that anarchists call themselves anarchists is that they are against all government–as they understand government. If you want to introduce your own definition of the word “government,” which includes absolutely any arrangement for cooperation between individual people, no matter how informal, consensual, non-territorial, non-monopolistic, and accountable to external constraints of justice, then you’re free to use the word “government” that way, but your definition of the term (which I think is much further from the common use of the term than anarchists’ definition) would seem to be of little help either in understanding why anarchists call themselves what they call themselves, or in advising them on what they ought to call themselves to maximize clarity.

What they are not willing to do, and what no man [sic] should be willing to do, is to deprive the many in favor of the few,

I don’t see what numbers have to do with it. Of course it’s terrible when the many are forcibly deprived in favor of the few, and this is what almost always happens under the auspices of government (even so-called majoritarian government), where the governing class is always an elite minority parasitic upon the productive labor of the governed. But is it any less terrible when the minority, or an individual person, are forcibly deprived in favor of the majority, which has certainly also happened over and over again in history? (Cf. Socrates, Jesus, the Christian martyrs, Catholics in Reformation England, Protestants in Counter-Reformation Spain and France, Jews and Muslims and Romani all across Europe…) The only reason I can see why “the many” would, as a group, be entitled to demand that they will not be beaten or robbed or swindled by an elite few is because each of them, naked and alone with nothing other than her humanity, is just as entitled to demand that she will be beaten or robbed or swindled by anybody else, whether they are few or many. That’s rights, as I see it, and everybody’s got them whether or not they have a large enough posse.

Re: Smearbund Funnies

Have I been inducted into the Beltwaytarian Illuminati without having heard about it? If so, I eagerly await my imminent influx of cocktail party invites and Kochtopus cash.

ThorsMitersaw,

The declarations of states are not reflective of their citizens …

No, but they are reflective of the opinions of the state governments at the time that those state governments determined to secede.

Of course, many if not most people in many southern states at the time felt differently. For starters, many if not most people in many southern states at the time were black slaves.

The white southerners who fought as common soldiers often had very different views of the import and justification for the war than those held by their governments. But of course it was their governments, and not they, who made the political and military decisions that we’re discussing here.

Charles H.,

I agree with you that any honest review of what the secessionists said (especially what they said at the time of the secession debate, rather than when they wrote their memoirs in the 1870s) would very quickly reveal that the perpetuation and expansion of race slavery was absolutely central to the Confederate cause. However, it would be an ignoratio elenchi to follow that evidence with the conclusion that ending or limiting race slavery must have been absolutely essential to the Union cause.

When people claim that the Southern states had the “right” to secede, what they mean is that a minority– adult white male landowners– had the right to decide for everyone else what form of government they would live under, and whether their basic human rights would be recognized.

I’m sure that when many people claim that, that is indeed what they mean, but I don’t think it’s at all fair to impute that meaning to most of the writers at LewRockwell.com or the Ludwig von Mises Institute.

Whatever faults they may have (and some of them have a lot), most of the people in question are anarchists, who believe that no government whatever, state, federal, or other, has any legitimate right to compel anyone’s allegiance. Their point about the right of secession is that adult white male Southern landowners had a right to determine for themselves (and themselves alone) what form of government, if any, they should live under, a right which any principled and honest believer in the principle of government by consent would have to concede they do have. The obvious and hideous atrocity of southern race slavery hardly justifies military invasion and bayonet-point Unionism; what it justifies is the (Garrisonian) strategy of embracing peaceful disunion, and then supporting southern slaves in their efforts to secede from the from the illegitimate government created by their quasi-secessionist slave-drivers.

If you’re not already familiar with it, I’d like to recommend J.R. Hummel’s excellent book, Emancipating Slaves, Enslaving Free Men, which ably defends the Garrisonian-disunionist position and presents a much more accurate and sophisticated libertarian analysis of the war than the stuff churned out by, for example, Tom DiLorenzo or Tom Woods.

PhysicistDave,

I think the issues at hand are a bit more complex than cultural affinities. When I see Yankees like Tom DiLorenzo running around affecting a fondness for the ol’ Moonlight-and-Magnolias, I just find it ridiculous. But when I see them actively distorting history for polemical purposes, in order to whitewash rabid slave-driving statists like John C. Calhoun, Robert E. Lee, or Jefferson Davis (cf. for example 1, 2, 2, 3, etc., not to mention DiLorenzo’s periodic attempts to portray Lysander Spooner, the author of the Plan for the Abolition of Slavery and a conspirator in an abortive attempt to rescue John Brown from the gallows, as an advocate for “peaceful” gradualist emancipation, I think there is something deeper and nastier at work that needs to be exposed and confronted.

Of course, those people who, in the name of “moderation” or “compromise” or politesse, attempt to water down or dissemble about libertarian principles on hard cases, or who try to marginalize radical libertarians for simply for making uncomfortably libertarian points — a group that intersects with, but certainly does not exhaust and certainly is not limited to — the staff at Cato and Reason deserves nothing but contempt for that kind of hand-wringing opportunism. But I don’t think it’s true that that’s the only reason that the Paulitarians and the VMI/LRC crew draw the kind of flak that they draw from within libertarian circles, or even from the Cato and Reason crowds specifically.

Re: A saner era? Myths about trans kids in schools, courtesy of FOX News

Holly:

Thank you for posting this. I love how the genital correctness blowhard brigade keeps falling back on the idea that anyone who doesn’t go out of their way to make life unpleasant for this kid (e.g. by refusing to call her by her chosen name, or by harassing or punishing her for wearing the “wrong” set of clothes to school) must, therefore be “bending over backwards” to suit her delicate sensibilities. Rather than, you know, just not going out of their way to be obnoxious to an eight-year-old kid in the name of heteropatriarchal social engineering.

ThickRedGlasses:

Wouldn’t this child be considered disabled under the Americans with Disabilities Act? Gender Identity Disorder is considered considered a mental disorder, so shouldn’t this girl be covered by ADA?

I think we’d be better off not going there.

So-called “Gender Identity Disorder” is a basically political, not medical diagnosis. It’s been used repeatedly as an excuse for quack psychiatrists and anxious or controlling parents to inflict all kinds of torture, mislabeled “therapy,” in the name of “curing” their trans kids, or even mildly gender-deviant kids, of their “disorder”. In fact there is absolutely nothing wrong or crazy or disordered about a kid born anatomically male who wants to live as a girl (or vice versa), and I think it would be a serious mistake to reinforce and institutionalize the notion that there is, whatever short-term advantages you might hope to gain from it.

A few decades ago, Homosexuality was considered a mental illness and included as a category in the DSM. But if that diagnosis were still on the books, I think it would be counterproductive, to say the least, for gay liberationists to try and use it to get accommodations under the ADA.

Re: Gene Callahan Joins the Smearbund

Matt Polzkill defends Ron Paul by comparing him to Lysander Spooner:

What IS wrong with you guys?!? Who do you support for president? Who that ran, was light years closer to Spooner?

Meanwhile, Lysander Spooner joins the Smearbund:

SIR, — Your inaugural address is probably as honest, sensible, and consistent a one as that of any president within the last fifty years, or, perhaps, as any since the foundation of the government. If, therefore, it is false, absurd, self-contradictory, and ridiculous, it is not (as I think) because you are personally less honest, sensible, or consistent than your predecessors, but because the government itself — according to your own description of it, and according to the practical administration of it for nearly a hundred years — is an utterly and palpably false, absurd, and criminal one. Such praises as you bestow upon it are, therefore, necessarily false, absurd, and ridiculous.

… You have not so much as the honest signature of a single human being, granting to you or your lawmakers any right of dominion whatever over him or his property.

You hold your place only by a title, which, on no just principle of law or reason, is worth a straw. And all who are associated with you in the government — whether they be called senators, representatives, judges, executive officers, or what not — all hold their places, directly or indirectly, only by the same worthless title. That title is nothing more nor less than votes given in secret (by secret ballot), by not more than one-fifth of the whole population. These votes were given in secret solely because those who gave them did not dare to make themselves personally responsible, either for their own acts, or the acts of their agents, the lawmakers, judges, etc.

These voters, having given their votes in secret (by secret ballot), have put it out of your power — and out of the power of all others associated with you in the government — to designate your principals individually. That is to say, you have no legal knowledge as to who voted for you, or who voted against you. And being unable to designate your principals individually, you have no right to say that you have any principals. And having no right to say that you have any principals, you are bound, on every just principle of law or reason, to confess that you are mere usurpers, making laws, and enforcing them, upon your own authority alone.

… But the falsehood and absurdity of your whole system of government do not result solely from the fact that it rests wholly upon votes given in secret, or by men who take care to avoid all personal responsibility for their own acts, or the acts of their agents. On the contrary, if every man, woman, and child in the United States had openly signed, sealed, and delivered to you and your associates, a written document, purporting to invest you with all the legislative, judicial, and executive powers that you now exercise, they would not thereby have given you the slightest legitimate authority. Such a contract, purporting to surrender into your hands all their natural rights of person and property, to be disposed of at your pleasure or discretion, would have been simply an absurd and void contract, giving you no real authority whatever.

… Every man has, by nature, the right to maintain justice for himself, and for all other persons, by the use of so much force as may be reasonably necessary for that purpose. But he can use the force only in accordance with his own judgment and conscience, and on his own personal responsibility, if, through ignorance or design, he commits any wrong to another.

But inasmuch as he cannot delegate, or impart, his own judgment or conscience to another, he cannot delegate his executive power or right to another.

The result is, that, in all judicial and executive proceedings, for the maintenance of justice, every man must act only in accordance with his own judgment and conscience, and on his own personal responsibility for any wrong he may commit; whether such wrong be committed through either ignorance or design.

No one could justify, or excuse, his wrong act, by saying that a power, or authority, to do it had been delegated to him, by any other men, however numerous.

For the reasons that have now been given, neither any legislative, judicial, nor executive powers ever were, or ever could have been, delegated to the United States by the constitution; no matter how honestly or innocently the people of that day may have believed, or attempted, the contrary.

… Such, Mr. Cleveland, is the real character of the government, of which you are the nominal head. Such are, and have been, its lawmakers. Such are, and have been, its judges. Such have been its executives. Such is its present executive. Have you anything to say for any of them?

Yours Frankly, LYSANDER SPOONER. BOSTON, MAY 15, 1886.

The original “Goodbye to All That” is one of my favorite short essays in the world. So it’s a bit disappointing to see someone who once wrote this:

Beyond all known standards, especially those easily articulated revolutionary ones we all rhetorically invoke. Beyond—to a species with a new name, that would not dare define itself as Man.

Re: Contra-Anarchy

I dunno. I think people who use the word “anarchy” use it as a package-deal: it’s not that it means chaos instead of freedom from rulers; it’s used to mean both chaos and freedom from rulers, because people who use the word that way think that the two are the same thing, or at least inevitably connected with each other.

So when people are package-dealing, there’s two ways you could respond. You could reject the term and come up with a new one. But what would you come up with? “Peace?” “Freedom?” That’s what anarchy means, but obviously the common uses of those terms are just as knotty as the common uses of “Anarchy.” “Lawlessness?” “Ungoverned?” Both of these imply chaos in common usage just as much as “anarchy.” “A spontaneous, polycentric, or non-hierarchical social order?” Gag.

Fortunately, there’s another thing you can do when dealing with a conceptual package deal: you can pick out the part of the concept you want to preserve and defend, and then explicitly challenge the presupposition behind the attempt to package-deal it with the part of the concept you don’t want to defend. For example, this is what gay men and lesbians did when they reclaimed the words “homosexual” and “bisexual” from the psychiatrists; the words used to be used so as to imply both (1) having particular types of sexuality, and also (2) suffering from mental illness. The gay liberation movement embraced (1) but chucked (2) out the door, and it didn’t take too long for much of the rest of the world to catch up.

It might seem like taking the reclamation route is somehow a drain on time, since it gets you tangled up in other people’s confused terminology. But I’m not at all sure that’s right. Identifying and challenging the confusion that’s implicit in the ordinary use of the word — e.g. the confusion between lawlessness and riot, or the presupposition that only government force can produce social harmony — is part and parcel of the strategy of reclaiming the term. In some important ways, it involves you much more in meeting people where they are, whereas minting new language can lead you into inadvertently sidestepping the real issue, by not confronting the confusion that’s at the core of the dispute over the meaning of e.g. “anarchy.”

Re: Reader Mail #32

Kevin,

You’re right about the origins of St. Thomas’s Third Way. In On the Power of God, a work dated after the Summa contra Gentiles but before the Summa Theologica, he explicitly attributes the argument to Ibn Sina, with developments added by Ibn Rushd. (In fact, all of the arguments used in the Five Ways are explicitly attributed to other philosophers at some point or another in St. Thomas’s work.)

Re: Reader Mail #33

You wrote: What is “Thomistic”?

Of or pertaining to the thought of St. Thomas Aquinas, a Doctor of the Church and the leading figure of the revival of Aristotelian philosophy during the High Middle Ages.

St. Thomas famously believed that, although many of the mysteries of Christian faith could not be discovered by natural reason, and had to be revealed by the grace of God, there were at least some doctrines of natural theology, and in particular, the existence of an uncaused, necessary, and perfect Creator of the visible world), which could be proven through rational demonstration, and set out his Five Ways to prove the existence of God. The third of the Five Ways, the argument from possibility and necessity, is intended to demonstrate that there must be a single necessary being — i.e. a being which could not possibly fail to exist — to explain the existence of contingent beings — i.e. beings which do exist, but could fail to exist.

Kevin’s right about the origins of the argument; in an earlier book, Aquinas explicitly attributes the development of the argument to two Muslim commentators on Aristotle — the Persian philosopher-physician Ibn Sina (known in Europe as “Avicenna”) and the Spanish-Arab philosopher Ibn Rushd (known in Europe as “Averroës”). Generally speaking, a lot of the revival of Aristotelian philosophy in Christian Europe during the High Middle Ages was deeply influenced by the work of Muslim scholars a century or two before; indeed, without the texts that Arab scholars preserved and copied, the renewed interest in classical Greek learning in Christian Europe would hardly have been possible: most of the work of Plato and Aristotle, among others, had been completely lost in Western Europe for hundreds of years, until Muslim scholars re-introduced it.

Hope this helps.
