The news in America, amplified by millions of bot social media accounts, is designed to make us fight each other so we are distracted from our real enemies.

You can go outside and talk to strangers any time any where and have an experience much nicer than anything a foreigner would expect to see based on our news.

Some of that comes from cognitive dissonance. I know people who parrot the hate from the news and social media perfectly after 2 beers. Put a real person in front of them in the real world and they are nothing like the talk.
