There is such a thing as neo-nazi folk, though. I don't think it's very common, but it does exist.

I read a story in a music magazine about a somewhat famous neo-nazi who lived not far from me who did weird occult rituals in the woods, and who I believe was a member of the Order of the Nine Angles, an incredibly extreme group. Pretty scary stuff.

I'll see if I can find the link to the story

Edit: here you are. CW for sexual assault, racism, grave desecration, and occultism.
