How I see it is if hypothetically the Supreme Court reversed America back to separate but equal, it would be up to most states to pick and decide what they want to do similar to how abortion was after the supreme Court decision.

I also agree about having issues with cultural isolationism. Most of my whiter family members would admit to having African DNA before many of my darker ones specifically in New York and the Caribbean. There is an exception to my family who ended up in the south ironically. I have also seen the problems with immersing yourself in white American culture during the 80s and 90s as this is where the idea of the token negro was invented and I see family members again don't admit to being black and making similar black jokes as a white middle aged person.
