Race relations were set back to the 1950's, if not earlier..
When I was in high school during the 90's, we had quite the mixing of black, white, asian, and so forth. Groups were so intermixed that racism wasn't really an issue.
My brother went to school in the 80's. The mixing was just starting, but it wasn't white vs black. It was just people.
My oldest brother was in school during the 70's. There were racial divides and tensions, but it was residual dying down from the Civil rights movement of the 60's.
The 1960's, black and white integration was being legislated.There were bad feelings as blacks and other minorities weren't respected by the white majority.
Go back to my parent's youth (1950's). The way they tell it, my father was severely discriminated against. He's 1st gen, Spanish immigrant. Whites were against non-whites and kept them in their place.
Contrast the 1950's to today. Now the races don't mix. They're more tribalized at my kids' schools. There's minimal crossover. If a black dates a white, the white is asserting their privilege. The black is a traitor to their kind. That's 70 years of progress that's flushed with Obama supporting BLM and other race based groups.
What we need is to recognize that we're all human. Sure people will tribalize, but you don't address the tribes. You address the commonalities across all people. There are shared values that everyone holds. Use those values to unite people.
