I was gonna say "fundamentalism does not always imply religion," but I read a few of his posts and he's definitely a nutbar.

E.g. "The females of all mammalian species, including humans, always have more power than the males, and, in every human society, women are slightly better off than men are." (Based solely on longevity and reproductive success, "the only two biologically meaningful measures of welfare.") It sounds like he's one of those "women are better off than men because they can get laid whenever they want and I can't" guys.
