This is a very complicated topic and I will be happy to write at length on it. I grew up in in northwestern Louisiana in the late 1970’s - early 1990’s. Would you believe me if I told you that we had segregated schools until 1980? Believe it or not, it was a fact despite what your school books will tell you. Both of my parents taught at the black school and my grandfather was not only the president of parish school board, he was also the head of the national one as well.
My town kept segregation until 1980 through a technicality. We were a very small town and whites literally lived on one side of the railroad tracks and blacks on the other so all you had to do was to draw two separate school districts dividing the town of 1,300 people in half to keep it segregated. The courts finally noticed and my grandfather had to come up with an integration plan starting in the late 1970’s. He received so many death threats for it that it was probably a contributing factor in his early death at 55 in 1982 due to heart failure.
The above may make it sound like we were a progressive family in a backwards area and that is true in a way but completely untrue in others. We were fighting the white trash of the area which had a completely different view than the teachers and other professionals that lived there. White trash is the lowest form of person there is and we didn’t tolerate them to any degree. On the other hand, my family is really conservative in general but fair to everyone and we do not agree with modern progressives about anything significant.
Being nice to a black person was never forbidden in the South and it was never uncommon at all. That would be crazy because there are different unofficial ranks of black people even in the most racist societies. Some of those are quite high and surpass even biological family members. You protect them like a best friend even with your life. Most people, me included, were partially raised by black nannies who we loved dearly even more than most of our biological family members including your own grandmothers.
I am 40 years old and my nanny, Lola ,only died 4 years ago. She was old when she got me at 17 months old and stuck with me until the end when she was over 90. I still tear up when up when I think about her but we stuck together until the end and I always went to see her when I went back home. She still had pictures of me and my brothers as well as my daughters on her walls in the nursing home the last time I went to see her mixed in with her biological grandchildren. That is just the way it works in the Deep South.
Threads like this make me realize that many people have no idea what they are talking about because they are trying to visualize something that they have no real reference points for. Blacks are a majority in many of the cities in the Deep South (New Orleans has been majority black for a very long time for example as are most of the large cities in Louisiana; many of the smaller towns like my home town are roughly 50% black).
There are some people that are quite racist but you will go insane in short order if racism is a major thought process in the Deep South. Everybody gets along just fine on a day to day basis even if there is limited voluntary segregation in lifestyle choices like church services. If it weren’t for the younger black male demographic, everything would probably work out even better. I have a few black male friends from my home town that made good. The rest crashed and burned in the prison system. OTOH, I had a few surprises. A black woman from the absolute worst family I have ever encountered (literally; almost all the rest of her family has been or is in prison and some of them for life) just made full Bird Colonel in the Air Force and I am super-proud of that achievement knowing the situation she grew up in.
I live in the Boston area now which has a serious history of racism of its own. The ‘enlightened’ solution to racism here seems to be to price out all the undesirables out of the state and then comment on how it could be done better from the safe confines of exclusive mainstream white and Jewish communities.
Racism isn’t a solved problem in the U.S in the least and I don’t expect it to be in my lifetime. However, I do not like race relations in the U.S to be misrepresented by people that probably grew up in a non-Southern city or suburb. It doesn’t work the way you think it does and never has. You can always find examples examples of atrocities but tjose are not typical.
