I think it actually says a lot about the "innate superiority" of white people. They think they are superior, but actually they are not as smart as people of color. Hillary was obviously a better choice than Trump in terms of economic and political self-interest for all those white women, and yet they voted for Trump.
White women in particular are much more gullible than women of color. Female misogyny is a real thing, and maybe enlightened women need to help their sisters to learn to reject it.
