Voting in Biden isn't going to immediately fix everything. Obviously replacing Trump's cabinet will have a huge effect, but Trump has damaged America so much that it might never recover.

America is broken. And yeah, it's probably due to the power of social media. Those of us in our late 30's early 40's have witnessed the birth and growth of the internet, and there's no way we would have heard of people believing in flat earth, QAnon, and shit like that even 10-20 years ago. It's mind blowing. Somehow all this access to information is able to make a certain percentage of the population stupid. Even respectable people that you'd never guess to be "that type of person" are susceptible to it.
