Gender, sexuality and sexual norms are the great unPC problem of LessWrong.

I've decided to bow out of this thread -- as I've not significantly studied either PUA, nor cared to read about previous PUA-related threads in LessWrong, I can barely understand what you're talking about. Perhaps you've noticed a real problem that I haven't, exactly because you're focusing on different type of threads than I do.

The thing I had in mind was things like e.g. the guy who repeatedly and deliberately kept using the diminutive word "girls" to refer to female rationalists but "men" to refer to the male counterparts. This by itself -- when I perceived he intended to belittle women in this fashion, or at least didn't give a damn about not insulting them -- prevented any meaningful discussion of the actual argument he was engaged in, (whether a male-only meetup would be useful or detrimental for the purposes of LessWrong).
