1. He openly endorsed the Green New Deal, universally recognized as the stupidest idea anyone has ever presented in American politics.
"No, I don't support the Green New Deal. I support the Biden plan that I put forward, which is different from what Trump calls the radical Green New Deal." - Biden at 1:22:35
2. He made no condemnation of the riots and domestic terrorism plaguing America.
"Violence and response is never appropriate. Never appropriate. Peaceful protest is. Violence is never appropriate." - Biden at 55:55
"I've made it clear in my public statements that the violence should be prosecuted. It should be prosecuted. And anyone who commits it should be prosecuted." - Biden at 1:03:22
3. His COVID argument literally consists of "This international plague is somehow Trump's fault."
His argument is not that the virus is Trump's fault. It was 1) Trump knew about the Virus in February but downplayed significance to the American public; 2) Trump was not harsh enough with China's president insofar as letting U.S. health experts investigate in Wuhan, and Trump praised Xi for being so transparent; 3) Trump's administration did not provide enough protective gear, or pass the other House bill to provide money that would provide PPE, ventilation and other expenditures that would allow schools and businesses to remain open.
4. His economic argument is "you killed the economy" but at the same time "we need to close the country"
Actually he spoke against shut downs. He said the reason the economy had to be shut down was largely in part to Trump's negligence, and had he taken certain measures - specifically telling the public about the virus sooner; emphasizing the seriousness of the virus rather than downplay the 'hoax' of concern; encouraging everyone to wear masks; and providing PPE to critical establishments among other things, that businesses would have been a lot safer to remain open. He said "If I were running it, I’d know what the plan is. You’ve got to provide these businesses the ability to have the money to be able to reopen with the PPE, as well as with the sanitation they need. You have to provide them classic-" before being interrupted by Trump.
Then Trump says "Well, he wants to shut down this country and I want to keep it open, and we did a great thing by shutting it down" to which Joe replies "You just admitted you'd shut it down." Then Trump accused Biden of wanting to shut the whole country down, and before Biden could reply Chris Wallace interrupts and says they need to move on. Biden demands a chance to respond 2x and both times the moderator wouldn't let him.
But it's clear that Biden's proposal is not to shut down - it's to spend a lot of money allowing businesses to stay open.
5. Weirdly enough, Biden hurled more insults at Trump than vice versa. This was the time he was supposed to be the grown up. Instead, they both looked childish.
How would we determine this considering there is no way to quantify tone or sarcasm? What we can do is tally the number of insults and interruptions, but that wouldn't say much about the breadth of the dig (like some insults are worse than others). For instance Biden told Trump to shut up and called him a clown, but Trump mocked Hunter Biden's drug problems. I'm curious what your metric is and then I'll be able to go back and see if this is true. Trump interrupted 70+ times; Biden interrupted 20+ times if that counts for anything.
