I understand your frustration, but the PUA case is different: you get lots of people denouncing it who do not as a rule denounce lifestyles very different from their own. Including, for example, some LW members.

BTW, if all the people around me reacted with hostility to unfamiliar ideas, I would, first of all, try to rule out myself as a factor (e.g. maybe I'm annoyingly preachy w/o knowing it?), and if that didn't clear things up, look for better people. Well, actually, I don't know if I'd do that, but I'd like to think I would.
