Does America have problems? Yes. Does every other country in the world have problems, too? Yes.
Look at other first world countries. There are far higher levels of bigotry in Britain, Germany, and more. In Britain, there's a major political party that's whites-only. The only black figures in Playmobil drive garbage trucks, or do other low-level jobs. Hell, even in New Zealand, homosexual acts were illegal until twenty years ago.
Long story short, shut up.
