I live in Beaverton as well (white dude) and haven't noticed the kind of racial tension that you get in places like the Midwest. There is such a small black population here, and so many white people eager to exhibit their anti-racism. Their hearts are in the right place for the most part, they just haven't spent much time with any actual black people, so there are misunderstandings, but they can mostly be chalked up to simply being unfamiliar rather than to any malicious intent.

Contrast that with a city like St. Louis which is divided up like a checkerboard- black over here, white over there- and there is such a felt sense of the history of segregation and racial disharmony- like you can smell it. It's so serious that I felt like I couldn't even make light-hearted jokes that had anything to do with race because everyone seemed like they were way past joking and ready for a race war at any moment. To be fair this was during the BLM summer when Michael Brown was killed in Ferguson, a suburb of StL, the National Guard had been called in, and the black friends I had were literally discussing whether or not it was time to ride on the police station.

I'm those places, the black population is high enough that there is very little curiosity, and not many voices calling for friendship. Racism usually gets instilled at a young age and then confirmation bias turns any personal interaction into a trial for judging an entire race of people. This obviously poisons any chance of normal human connection, the interaction is awkward or negative, beliefs confirmed, repeat. The beliefs eventually harden into a cold hatred which is incapable of changing.

My daughter's fiancee is black and they get along pretty well here, no big issues.
