I have traveled in some of the most socially liberal circles in the US, and I have to disagree with you about what's popular - or at least make it much more specific. It's not popular to claim that there are significant, biologically-determined, mental differences between men and women. Small differences, cultural differences, and corporeal differences are all accepted. This zeitgeist may still be incorrect, but it's not terrible as a heuristic.
