Technically, as much as I dislike it, there is nothing in liberalism to predispose a person towards racism.
Then why are so many self-proclaimed liberals/pro-western people so goddamn racist/chauvinist towards anything eastern?
Furthermore, Eastern liberals often hate their own country and get a hard-on for NATO/US invading them.
Media bias, I would say is a massive part.
They are told time and time again, we are a lucky place to be, over there is a totalitarian abusive place. Russians bad, Chinese bad. So it becomes “I’m not racist, that’s just how they are”, based on their worldview.
