If you follow that rabbit hole you find that the Nazis had this whole batshit crazy alternative science. It was sort of like Lysenkoism in spirit (an ideologically conforming “alternative truth”) but zanier and wilder. Think hollow Earth and mystical traits of the Aryan race and such.
I heard a historian once describe the SS as “what you would get if you made the Church of Scientology a branch of the military.” The Nazi party was kind of unique in that it was more of a cult with a political party than a simple political party in the classical sense.
I speculate that this is why the Nazis are such a symbol of evil in spite of Stalin having a similar body count. It’s the same reason the Manson murders are creepier than your average serial killing or shoot ‘em up. The culty stuff gives it this extra layer of dark edginess. Stalin just wasn’t as edgelord.
Nazi mysticism and volkisch stuff lives on in the New Age and other areas which is why flipping people in those worlds to Q and other thinly veiled fascist cults was so easy. There’s already a ton of esoteric fascist memes floating around that world.
