I’d warn against the idea that Hitler was somehow indispensable to the movement.

I think MAGA is instructive here. Do you think Trump is an evil genus, or just a lucky blow-hard carried by the worst impulses of the right? Fascism is popular, and we need to stop acquitting the societies that nurture it.

To answer your question, I’d ignore the fascist leader and the rabid followers. I’d find a scheme to impose social and financial costs on those who don’t support fascism, but are wiling to tolerate it for their own interests.
