Nazi really believed their own ideology. They did not cosplayed hating Jews, Slavic or homosexuals. They were scapegoats because they were hated.

It is the same here. People scapegoat who they dislike.

They do though. They mention obscure authors and theories about white replacement and neo-eugenics. There's constant controversies of people finding the online handles of these power players on sites like gab and bitchute where they express pretty unambiguous sentiments.

Musk has a trans child he's cutoff all contact with. There's very little evidence these people are faking it. There's never been a group chat that gets leaked to expose them as secretly fine respectable people.

We have this tendency to think socialist and leftist are all very serious about it while the people on the far right don't actually believe it, they're just pretending.

Nonsense. They're for real.
