Bill: If it’s “oppression”, then the voluntary arrangement fundamentally implies an injustice, a victimization, and, yes, an aggression …

“Hey, if I re-interpret your statements about oppressive social relationships according my definition of ‘oppression’ in terms of aggression, which you just explicitly rejected, then you end up with an inconsistent position.” Well, yes … yes, I guess you would.

Bill: If it’s okay to engage in directing social opprobrium at people engaged in voluntary behavior you find objectionable, why would it be wrong to impose a tax on them? …

Because “social opprobrium” is a voluntary process involving non-violent social relationships, without the use of legal sanction or physical force against your person or your property. Taxes, fines and jail obviously are not.

Social reputation, social tolerance and social approval are the products of other people’s opinions and choices; but while you own your possessions, and your body, you don’t own other people’s opinions of you. if they choose to cast opprobrium on you for non-violent but oppressive behavior, then they are within their rights on most any minimally libertarian theory.

Of course, it might be that in a particular instance they are acting wrongly, even if they are not acting aggressively — people can use social opprobrium to harass and to bully and to dominate and to exploit the vulnerable even though they are not violating anyone’s rights to person and property. Certainly anyone who advocates the particular “thick” conception of libertarianism that I am defending would agree with you there. But then in order for you to help yourself to the claim that there is something wrong with this kind of misdirected social opprobrium, you must accept the claim that people can act oppressively towards each other without acting aggressively. Which is precisely the claim you were trying to deny.

(My own view, on the contrary, allows for a fairly simple understanding of what’s going on: social opprobrium is not force; it is a social process which can be used either rightly or wrongly; but when social opprobrium is used abusively, oppressively, or in some other way wrongly, then the way to deal with that is to respond to it in kind — with solidarity and social activism of your own, but used rightly and supportively. The reason you shouldn’t use taxes, fines or jail is because physical force is only justified by defense of person and property, and what you’re combating here, while abusive, is not a violation of your rights to person or property.)

Bill: That means that they view these voluntary choices of others as oppression.

That’s correct, the thick conception of libertarianism they (I) defend includes an explicit claim that voluntary social interactions can be oppressive without ceasing to be voluntary. I don’t see this as a problem for the view. I see it as the point of the view.

Bill: Unless they assume some massive amount of masochism on the part of those they’re claiming are oppressed, they’ve given themselves veto power over legitimacy of the voluntary interactions of those who don’t adopt similar attitudes …

I don’t know what kind of “veto power” you have in mind. If you think that a position against non-aggressive forms of oppression involves some tendency to individually disapprove of, or, say, to non-violently socially stigmatize, at least some behaviors, interactions or relationships which are admittedly voluntary (in the sense of being acted out through strictly non-aggressive means), then of course you are right about that. But is that “veto power” in any meaningful sense of the term? Certainly not in any meaning of the term that involves an exercise of aggressive power. Again, the point of the view, as stated by those who advance it, is to provide some considerations in favor of addressing non-violent social problems through non-violent social means. (Rather than, say, holding that there just are no non-violent social problems, by definition.) If, on the other hand, you think that calling X “oppressive” means assuming “veto power” over X in the sense of legitimating the use of political force to repress X, then, again, that is what the people in question (me included) explicitly deny, and have denied all along. (See for example this discussion of “the authoritarian theory of politics.”)

Given that we have explicitly called for the use of non-violent social activism and cultural change instead of any use of political force to address the oppressive-but-non-aggressive dynamics that we’ve discussed, any charge that what we’re proposing must ultimately logically lead to criminalizing those dynamics seems to be completely unfounded in what we’ve argued. Of course, you might hold that social stigma, cultural politics, etc. can all be problems even if they are not leading into political force — you might hold that the attitudes we take are, say, narrow-minded, or intolerant, or busybodying. And I don’t agree that they are, but you might have an argument for that. (Certainly I don’t think that “social stigma,” say, is something harmless when misused, even though it may be non-aggressive.) But then of course you too are advocating a thick conception of libertarianism — just one which connects libertarianism, say, with a very broad norm of social tolerance, and which exercises a great deal of skepticism towards any sort of social pressure or conscious non-violent activism, rather than with the sort of anti-oppression activism that I have tended to promote. And the argument is not going to be an argument about whether libertarianism should be conceived thinly (as a demand strictly independent of other social or individual norms) or thickly (as integrated with other, interlocking commitments) — it will just be an argument about what other commitments a thick conception of libertarianism ought to be integrated with.
