Nazism, like all forms of fascism, falls apart without an enemy. Even if they managed to kill all the Jews and Slavs, people would still be murdered on the suspicion of being Jews and Slavs for as long as Nazis are in power.
i've long held that if fascists couldn't designate a racial or national enemy, they'd play up the distinction between men and women as their primary struggle. And if they couldn't do that they'd go after certain age groups. They'd find something.
i think that's part of the reason fascists in America have latched so heavily onto being anti-LGBTQ. They're slowly realizing that open racism is broadly unpopular, so they're flailing about trying to coherently designate a different enemy. What they fail to realize is unspoken racism is perfectly permitted in America, but they can't help themselves. They have to say the quiet part.
I agree though I think the main strain of Fascism in America is Christian fascism, which colors their hostility towards LGBT people and ideas. Trump was popular among that type because he basically declared that open racism is back on the menu.
I think those people are drawn to anti-LGBT stuff because if you aren't LGBT to begin with it's a very easy set of rules to follow. And they would like to in order to claim to be religiously righteous follow at least some rules they can tangentially trace back to the bible and all the actual stuff the new testament and bible tells you to do is too hard so they picked one rule in leviticus and arbitrarily decided that one is really important. Which is pretty stupid because they don't do the same for the other rules in that section like not shaving, no tattoos, no eating pork, be nice to immigrants etc
they would have just defined a new previously accepted group as evil. Maybe people from the mediteranean, indians, asians, africans, the french, the english, etc as long as they were around they would have found someone. All it takes to be racist is wanting to because you can just pick any arbitrary group and racialise them due to the fact the whole thing is arbitrary to begin with
