Anyone from southeast Asia will tell you how good race relations are in the USA. In S.E.A. every ethnic group HATES the other. Well, in all of Asia really. and in Africa. Well, in most places except the USA. Other places like Canada pretend they are better on race, yet how often do you see a black politician in Canada or Germany? Japan may be the absolute worst but China rivals them. It’s hard to pick the worst since tribalism and bigotry are the human norms across the world. Ever listen to an Irishman from County Clare talk about those scum from County Cork? Lol.
Despite the best efforts of the Marxists and race hustlers amongst us, most of the USA tries to hang onto e pluribus unum and our melting pot ethos.
