Maybe it's a political correctness principal component, but it seems to me that ideas about status should not be aligned with that component. If PUA had not been mentioned, and we were just discussing Johnstone, then I think those who are ignorant of PUA, whether pro- or anti-PC, would have less extreme reactions and often completely different ones.

If people's opinions on one issue are polarizing their opinions on another, without agreement that they're logically related, something is probably going wrong and this is a cost to discussing the first issue. Also, cousin it talked about the issues creating "camps." That's probably the mediating problem.
