Yeah, a lot of it depends on location considering our country is so large. I grew up in NYC and rode city buses to school. We couldn't be more diverse and we got along well. But again that was NYC.
I do believe the future is bright though, if we can try to understand one another. My current medium-sized city is very diverse, even politically - Biden and Trump bumper stickers were about 50/50 in 2020. It's very peaceful even if we don't agree on everything.
