Don't insult my intelligence. I've got two degrees myself, one in History and Politics and an M.A. in History. I don't throw my education around, it's not necessary to do so. I'm perfectly aware of Godwin's Law and assumed that would be the thing to pick up on. I do not expect American democracy to crumble overnight, but if you think everything is tickety-boo with US institutions at this moment in time, then I would suggest you look a bit closer. Public trust in their institutions is at an all-time low, misinformation is rampant. The divide between left and right has been larger before but the animosity and distrust that both sides feel towards each other is worse than it's been in years - remember in other significant crises like Watergate, even the majority of Republicans believed Nixon was guilty. The partisanship that emerged in the 90s with Clinton and Gingrich has been ramped up by perceived, or real, injustices, particularly since the 2008 financial crash. In 2008, Obama was elected and Palin was unleashed onto the national stage. In 2010, the Tea Party became a political force. By 2012, Birtherism was a thing, despite Obama releasing his entire birth certificate. In 2016, Trump won the Republican nomination and then the presidency. In 2020, Trump supporters refuse to accept the result of the election and storm the Capitol Building. Trump isn't disappearing any time soon. Is that not a pattern? He'll have plenty to say post-presidency, whether that's with his TV Network or wherever. His supporters won't disappear, because this isn't just about Trump. It's about QAnon, it's about anti-vaxxers and coronavirus. It's about all these myriad of reasons why people feel violated or disenfranchised.
You're right, the United States will most likely survive. It is a 'very resilient country with a strong democracy and strong institutions'. But it still had to fight a Civil War 150 years ago (the flag of the secessionists made it into the Capitol Building for the first time in history today). It also survived the 1960s, but not without the death of a President, a frontrunning candidate and 2 iconic civil rights leaders. I wouldn't consider that a particularly stable democracy. I sincerely hope that this is the watershed. The dying of the light. The point where those who have been ambivalent about Trump and his antics draw the line and say 'no more'. But the fact it got to this point is itself damning. I wish I could just laugh it off and dismiss it as you do. But haven't we laughed off enough in the past decade plus and ended up at this point?
