This is true, but it's amplified by the ugliness that you yourself don't realize is being pushed by malicious actors. Hateful, untruthful memes, conspiracy theories, Reddit comments, Twitter posts, and more are being constantly generated by entire buildings full of people who barely know what role they are playing in providing fodder for Infowars, Fox News, and the rabid extremists looking for hateful storylines to retweet, share, and like. All of that filters down to regular innocent people and distorts what seems like normal, what seems fringe, and destroys trust in everything a person sees or reads online. Sure, a lot of this is just people at their worst, and Americans being themselves, but your reluctance to admit that it's partially fueled by organized forces that don't have any particular mission beyond sowing discord and chaos is part of the problem here.
