I don't know, I think it's more an issue of mindset. I think a large reason a lot of women (although plenty of men, too) avoid and outright hate any non-woke racial unification is because of naivety. many people are surprisingly naive, and this isn't really their fault, and while intelligence definitely plays a role, psychology almost certainly does as well. If everyone always tells you everything is alright and you pruposefully echo chamber yourself so you keep hearing "nothing's wrong here" you'll believe it.
