Biden is neoliberal (neocon?) war criminal and has been since before he even became Vice President. But let's really not be the "actually Trump 2024 is good actually compared to Biden" people. It's not only a bad look, it doesn't reflect our beliefs or principles.
Maybe the couple posts I've seen about this is :fedposting: but Trump is also a fascist and was doing heinous shit with his power too. Not to mention he'd use the post to pogrom trans people. And all of nakedly fascist stuff he did to suppress the 2020 BLM movement (unmarked feds disappearing people in vans??? Thumping a bible on the steps of the capitol while Feds teargassed protestors???)
Fuck Biden and Fuck Trump and fuck anyone who tries to carry water for either of them.
But to be less irony poisoned, it's a very tricky word to define specifically. I generally call actions facsist if the government is using violence to suppress popular power or subvert legal norms. So of course you could call every police force in America a fascist occupying force (and I wouldn't disagree with you) and you could also call every American president fascist as well. That's why I said Trump was "nakedly fascist" with his use of force where Obama and Biden are more polite fascists.
