OK, those things have indeed happened, to some degree. Above comment corrected.

I still don't understand what is uncharitable about the Wordsx3 post specifically. It accurately describes the behavior of a number of people I know (as in, have met, in person, and interacted with socially, in several cases extensively in a friendly manner), and I have no reason to consider them weak examples of feminist advocacy and every reason to consider typical (their demographics match the stereotype). I have carefully avoided catching the receiving end of it, because friends of mine have honestly challenged aspects of this kind of thing and been ostracized for their trouble.
