Truly the weirdest consequence of crank magnetism and conspiracy syncretism is the kinds of bedfellows you find. UFO cults align with Christian dominionists because the aliens are actually demons (or vice versa - which direction isn't important).
It feels like modern fascism is less driven by orthodoxy (right belief) than they are by orthopraxy (right action) to the degree that as long as they aren't actually in power anyone who hates on the right people and rejects the right facts can join the same club regardless of what they actually think. The weirdo occultism of the Nazis was largely tied to the project of reifying their racial hierarchy in all aspects of society by establishing that the Aryan race had the best religion and the best history in addition to the best genes and the best country. The weirdo occultism of modern fascism doesn't have that kind of thread to it that I can see, and I don't know what that means for ongoing development. Does it turn into a source of internal strife as they get closer to having actual influence? Do they settle into a more specific doctrine and cull the ranks of those who don't adopt it? Or is accepting a consensus reality actually the optional part here as long as the group can broadly agree on what to do?
