Well I do think he is “casually” racist but not serious. Like it’s not a guiding ideology. If it’s between making a scene or shaking the hand of a colored person’s hand he has no problem with that. He doesn’t really give a shit. He’s a malignant narcissist, which means he is driven by the psychological need to be “the best and most amazing person”. Justifying that just because of his whiteness would probably almost be an insult to his unique greatness.

I also think his mind is in a kind of fugue state where he’s not fully conscious, like sleepwalking. He’s more like an LLM that is constantly throwing things out “to win” and his mind is optimized to do that very well. If you’d institutionalize him, put him on medication to calm him down and then slowly and calmly begin talk therapy you’d probably find he’s just a standard narcissist without any special ideology. Possibly Hitler was similarily “out there” in that regard, but they actually and truly believed in their ideology. They also believed in their nation and making it great, which Trump doesn’t give a shit about either.

You can define fascism (including racism or sexism) as a “sincere belief in inequality based on identity”. He certainly believes in that, just only for himself. In comparison, neoliberals also have a sincere belief in inequality, just based on class / wealth.
