There is no ideological coherence of fascism. It's about coercing a nation into elevating a chosen group/ identity of people above everyone else (a sort of anti-pluralism).

-- I liken it to how arguing about the shortcomings of your bully's stance doesn't make them stop punching you.

EDIT: I'm going to add, that I think the solution at least begins with encouraging more shared experiences and spaces (like a movie theater). Most people want to be seen as well functioning in public limiting how much they might explore the nastiness of their own right wing echo chambers.
