Thanks. Like the CCP points. And def agree lots of the richest Americans would in fact be fine with a non-democratic form of government as long as they stay at the top (although many others would not be fine with that). Also agree of course that the US needs to start at home, especially (for me) on inequality and our racial history. Taking a principled stand internationally means applying those to yourself, too (just as it does for individuals).
Find your Biden rhetoric extreme/emotional/shrill (no judgments, just honest opinion). He won the election and that means legitimacy in the US, although obviously I agree with the Warren/AOC systemic injustice critique, although obviously neither of them is pro-insurrection and everyone on the Dem side accepts the legitimacy of the voting outcome.
Major issue for me on comparing the Philly speech to Trump is the necessity of pairing words/attitudes to actual facts/actions. Biden is saying the Repubs are a threat to democracy, Trump is saying the Dems are a threat to democracy (stop the steal etc), the salient point is not what they're saying, but whether what they're saying pairs up to what happened. Since the election wasn't stolen, Trump is wrong and Biden is right. That's not an attack on you or personal in any way, I just strongly believe the core component of critical thinking is not comparing he said she said but looking at what was actually done and then who's she said he said matches up to it.
