There's being critical and holding representatives to task, and then there's just being a useful idiot to a power-hungry group who is more than happy to enflame your grievances in support of their ascension.
Yeah, liberalism fuckin sucks. But fascism is worse.
The problem is that while you're technically right, you're just kicking the damn can further down the road. Biden will crush the left just like Obama did, while a Trump win would not only mean WE were fucking right, but it'd finally end this fucking bitch ass democratic party for good. And dear God does the USA need an actual left-wing party, both for electoralism purposes (lel), and actual organizing.
Yeah, I realize a lot of it feels moot, just because the Supreme Court pick means the fascists can sanction their corruption.
In a weird sense, my dream scenario would involve Biden winning and Trump using the courts to usurp it. Then we've got ourselves the most relevant way to kick the rest of Americans into gear, especially if the Democratic leadership is exposed with another, "Welp, can't do anything about it."
