How would Hitler feel about a black non-German man revering him and his body of evil?

Hitler saw the Japanese as, in his words, “yellow aryans”. He also had an Islamic unit in his North African army. As long as you were militaristic and agreed with his philosophy, you were on his team. He was not a white supremacist but a scapegoating fascist. A lot of his non-Jewish civilian victims were Slavs, especially Poles.
