Here. (See here also for an essay by Sarah Hoyt arguing that when leftists “speak truth to power,” they are generally the ones with power.) Basically, when people claim to be agitating for a powerless group, one expects that they will value things in a rational way, by which I mean that they will judge certain outrages (those involving murder, for example) as more heinous than others (those that are merely offensive). The feminists’ anger at a guy’s shirt and their lack of anger about all kinds of horrible outrages that Muslims have inflicted on women shows that they have lost perspective on things, are behaving irrationally, and thinking in terms of emotion rather than reason. In short, they aren’t being a bit helpful to women who are victims of the Islamists.
