Dude, this is a ridiculous cheap shot and you know it. I could just as easily go around telling those, such as Gordon, who attempt to give philosophical defenses of voting for Ron Paul, “The question is are we going to be concerned about winning a philosophical argument or are we going to be concerned about some woman dying in a back alley in 2010?” or “The question is are we going to be concerned about winning a philosophical argument or are we going to be concerned about some immigrant dying of dehydration in the Arizona desert in 2010?” Your argument cuts as much ice as either of these, which is to say, none at all. All the parties to this debate are arguing over issues that have real and grave human consequences in the near term.

As for radical feminist literature and action, Roderick and I discuss that at length in our essay, so it would be more productive to engage with what we said there. For what it’s worth, there’s nothing inherently unlibertarian about broad sexual harassment policies, free daycare or employer paid maternity leave (or, what radical feminists are more likely to advocate, radical transformation of the economy away from an employer-employee model and towards ownership of the means of production by working women and men). These ideas may be wise or foolish for other reasons, but libertarianism as such only comes up when we turn to the question of whether these kind of measures are to be attained through voluntary means or by means of the State. As Roderick and I explain in the essay, while there are many radical feminists who advocate State action, there are many others who distrust State action for practical reasons or even reject it entirely on principle.

You write: “I also recall prominent radical feminists arguing that sex between a man and a woman in marriage was a form of rape.”

Can you specify which radical feminist(s) you’re referring to and where she or they say this? (If you’re referring to Andrea Dworkin’s discussion of martial rape laws in Right-Wing Women, that’s not actually an accurate statement of her conclusion, but in any case you should know that even if it were, she was discussing the ramifications of a legal context has mercifully ceased to exist since the book was written.)

As for the radical feminist menace to the safety of men’s wing-wangs, the legitimacy of violence depends on whether it is aggressive or defensive. Given the radical feminist emphasis on the prevalence of violence against women, I’d suggest that even if that talk were meant literally rather than rhetorically, that wouldn’t necessarily be an objection to it.
