I used to be really into occult stuff and UFOs and shit and boy did that get a lot less fun when it kept leading to realizing how much of it was twisted up by literal Nazis.

Yep, you can always tell where the Nazis have been because you see some niche groups stepping up to throw them out of the space. If you’ve ever been like “huh, why the hell is the Fraternal Order of Pumpkin Carvers putting out a statement condemning racism?” It’s cuz fuckin’ Nazi interlopers.

If I'm not mistaken Pagans have a organization committed against hate coopting their religion, so that's also a great resource too.

There are several of these organizations, though I don't think there's a ton they can do besides police people under their umbrella and try to show that Nazis don't totally monopolize Norse Paganism, etc., which is fair enough.
