The idea that trump cares about "fascism", or is even capable of holding such high-minded political beliefs is some hysterical leftist nonsense. Trump is the type of politician that would support any topic "X" as long as you campaigned on the basis of "X is cool and trump is also cool". In our timeline X was cryptocurrency, antivax, Qanon, charlottesville protesters, etc. but it could have just as easily been environmentalists, gay rights activists, BLM, etc.
When most people talk about facism, they are referring to a regime like those under hitler or mussolini. I am pretty sure hitler and mussolini had actual political goals they cared about. There will never be a "night of the long knives" because there is nothing that trump even wants that's worth backstabbing his allies over. To use the word fascist is ridiculous, because he is just acting as a ouija board for his dopey supporters.
