Out in the real world there is so much nuance. There are actually black people who don't agree with BLM. There are intellectual people who don't think they need the vaccine. There are Democrats who are pro-life. There are Republicans who support gay marriage. There are bunch of undecided people on a bunch of topics.
We are not all on one side or the other. There is so much middle ground. I still believe most people are in the vast expanse of middle ground.
It just doesn't look that way on the Internet.
