it's not hard for modern fascists to repudiate Hitler. fascism is an ideology obsessed with power and display of power, and Hitler is unambiguously a loser. also, his style of fascism is extremely antiquated in the modern day.
"Um actually im not Hitler fan, im a classical Fascist and im actually a follower of this late 19th century Italian Philosopher called Maximo Fascismo"
The weird part is that a bunch of them claim to follow Mussolini, but Mussolini is even more of a loser than Hitler and it makes no sense if you're obsessed with "winning" and "strength"
