Thanks for your comment. I've googled since reading your post and found a Wiki piece on Wagner controversies. It makes my mental link to Hitler seem more rational! It gets worse as you read on since some people think Wagner subscribed to a belief called Aryanism, and that he held beliefs that Western society was doomed because of 'miscegenation'. I've moaned before on Mudcat about an English folklorist using that word, in connection with a song called 'The Bush of Australia'. I don't think it made me popular. But I don't regret it.
