One other thing about Richard Wagner. I don’t think he can be compared to what Refeinstahl did. Though he was an anti semite to be sure, as far as I know he did not actively contribute to any Jewish pogroms or anything like that. He didn’t make music that progagandized people or had as it’s intent to brainwash people. That Hitler and the Nazis used his operas to champion racial superiority long after his death cannot be attributed to him.
I also dislike the attempt to smear Wagner with Nazism but his mature operas were absolutely propaganda for his vision of racialist self-realization and the sort of ‘instinct over reason’ ideology that would eventually lead Germany to disaster. The Ring and Parsifal especially were tracts- complete with characters intended as Jewish stereotypes.
