The guy behind Omarchy is also likely not a Nazi
He once said London is worse because it has fewer whites. He used some shitty noncommital dogwhistle phrase like "native British" or something like that, but the statistic he referred to (and actually referenced when saying that) was about the percentage of white Londoners. When this was pointed out to him, he didn't go "oops, how embarrassing, let me adjust the statistics I referred to", or "let me clarify my point" or anything like that. He just whined that he wasn't allowed to have an opinion. Not what I'd expect from someone who said white nationalist stuff by accident.
So, is he a card carrying member of the early 20th century German National Socialist party? No. But I don't think it's overblown to call him a nazi.
