Earlier quoted context omitted.
Not where I live, rural America. All the insanity is _literally_ in the big cities. There are minorities out here and we all get along just fine. It's political groups and the media that get people whipped up into hatred for each other, not individuals or communities. The times have changed, and the media and agitators (no better term?) that don't want to admit they are part of the problem.
It can be nice in big cities too, maybe a little harder, but still pretty easy - all you have to do is remove social media and the clickbait/outrage web and life becomes pretty normal.
I think it's a bit reductive to put all that on social media and the web. People are packed together in cities, sometimes you smell piss while going to and getting back from your job, sometimes people make noise when you want to sleep, it's hard to see nature, it's hard to be alone, it's hard to escape the noise and the light, public transportation can feel suffocating, the air isn't clean, it's very hard to have space to grow some food or practice some hobbies.
Most of it is "normal" in that many people live like this. However, I feel like all that I mentionned has a negative impact on my mental health, and on the mental health of the people around me. One that could translate to people being more aggressive, more tense in general.
