Was a timeline where there was no civil rights movement at all possible? Say after world war 2 the US public decides to bring race relations to the way there were before the war, so California does not legalize mixed race marriage in 1948, and things like the desegragation of the US armed forces and the the NBA does not occur? I remember a survey back in WW2, and even Northern whites were not in favor of black and Whites mingling with each other in social settings. Basically was it possible to have a more anti black and racist US leadership after Roosevelt, say a viable candidate that is more racist than Truman was? Or a US leadership that was more unfavorable towards decolonization, say someone more racist than Ike decides to send the heavy bombers to help out the French in Dien Bien Phu? Or the West decides that the fact that Japan was defeated after meant that White racial superiority was really scientifically sound, so scientific racism actually gets amplified post WW2?
