My area of suburban/exurban Nashville has more black people by percentage than Itasca, very similar affluence, and high rates of bachelors and graduate degree educations.
So GTFOOH with this “Alabama cul de sac” shit. There are tons of black people in the south. And they’re a lot different for the most part than the black folks up north who have been mostly confined to inner cities.
I grew up in Boulder. It was as white bread as you can get. Two black people and one jewish person in my entire high school.
Not a lot of racism - because we weren't taught any racism because the minorities were basically a curiosity. No white candidate for office spent any mental energy on suppressing the black vote. If someone was having a tough time financially, they didn't have black people to blame it on. It wasn't that the people wouldn't be racist given the opportunity, it's that the opportunity didn't exist.
The presence of black people doesn't make you non-racist. It gives you an opportunity to let your freak flag fly, like the confederate flag in front of Custard's house there in Selma.
