An interesting thing I learned from Eleanor Roosevelt's biography is that Hitler used the USA's treatment of black people as justification for his treatment of Jews, and this was widely regarded *in the USA* as a reasonable point and a reason to stay out of the war: "we would have to stop mistreatment of black people".

And I've heard that when Nazis captured Americans, they would make this same argument to the POWs. Basically, "why are you fighting us, we're the same".
