The right is struggling with how to 'spin' its support for fascism and Nazism. It still wants to deny it is those things, while embracing them so closely, because it hasn't yet determined a way to 'spin' them. The same thing happened with its support for KKK-like racism and bigotry, as they supported the agenda while denying the labels, until they figured out the word "woke" lets them get away with it.
Antifa seems to be flirting with being a similar word to woke, letting the right lie they aren't for fascism, they're anti-anti-fascism. By shortening "Anti-fascism" to "Antifa", why, that's an entirely different thing than anti-fascism, that's a 'far-left terrorist group threatening the country'. That somehow works for them. Eventually, like Elon Musk's Nazi salute 'snuck out', it seems likely the mask will drop.
While 'support for Nazis' is still not close, they can start to re-write history to pave the way.
They don't actually need to 'support the Nazis' to support the essential traits of the Nazis, just as they can support the traits of the KKK without saying they support the KKK by changing the word to "woke". You might see people noting, no one ever talks about the good things Nazis did, for example. It's already begun a bit.
PBS reports Mark Kelly quoting trump, "“He commented more than once that, ‘You know, Hitler did some good things, too,’” Kelly recalled to The Times. Kelly said he would usually quash the conversation by saying “nothing (Hitler) did, you could argue, was good,” but that Trump would occasionally bring up the topic again."
Have you ever heard trump criticize Hitler? When's the last time you heard a trump supporter criticize the substance of Fascism? Ever?
