You can't have the 50s without racial segregation though.

Uh, yes you can. The 50s are simply affordable housing and good paying manufacturing jobs and manufacturing towns where nuclear families live. Skin color shouldn't even be a factor here.

Blacks as a whole are incompatible with civilization.

That's idiotic and racist. Being an American has nothing to do with skin color and there's many blacks I'd prefer to hang around with than some whites. All those blue haired whales for instance, many based blacks better than those. Oh and racist pos like you.
