When I started to wander out into the brick-and-mortar Pagan community, I noticed that there were a lot of people who believed in Norse mythology and Pantheon. Some Asatru, some called themselves Heathen, some Northern Tradition, etc. And when I'd talk about how I wanted to find out more about how Pagans relate to music, especially if any relate to Classical music, I found that some Norsefolk liked metal and Beethoven, and others liked Richard Wagner. Richard Wagner, for those who don't know, is hailed as having "revolutionized" music during the middle of the 19th century, and he did this via writing operas about Scandinavian 'sagas' and the 'Nibelungenlied.' I wouldn't be surprised if Wagner was the origination for a connection between Norse/Scandinavian spirituality and anti-Semitism.
I am against the man and his works. Alright, maybe not. Maybe I am confused and heartbroken that someone who could write such beautiful and moving music, on such a thoroughly Pagan basis, was a megalomaniac, an abuser, and a bloodthirsty anti-Semite.
