Trump isn’t a fascist. In action he is actually a pretty standard reactionary liberal. You will notice that Biden has continued the salient policies that made liberals call him a fascist, such as extreme and horrible border policies (Dems actually outflanked the GOP on this from the right), anti-China policy, and extending militarism (like maximum pressure on Russia via Ukraine).
He’s mostly just openly racist whereas the political class usually wraps itself in polite jargon bullshit before it fucks with a bunch of brown people.
