Perhaps that's it. But, I'd really like to hear from someone who has lived both north of the Mason Dixon line and in the South. Maybe that's you Bruce, I don't know. I've always felt while the South is painted as a Racial Dystopia it is much more integrated than the North. As in we all grew up together, having different experiences of course, but still in the same schools, churches, neighborhoods, localities (malls, the cruising strip, etc.) jobs, et al, relatively speaking.
I fully admit I could be way, way off here.
Generalizations get tricky since there are a seemingly endless number of actual examples that refute the generalizations.
The South went/goes to school together? Private schools were literally created to avoid going to school together and to this day, many(most?) that I have read about are still extremely segregated.
The South went/goes to church together? Mmmmm, that isnt worth getting into its so incorrect.
Sure there is some integration in the white private schools, integration into the black public schools, and churches. That togetherness is 1- minimal and 2- often by need instead of choice with regard to school.
I grew up in the Chicago burbs with an absurdly high % of minorities(culturally and/or racially). Indian, Pakistani, LatinX, Asian, Eastern Euro Balkans, and some black. The kids all played sports together, after 1st generation housing was not very unified and so neighborhoods were culturally mixed, and schools were heavily mixed(both public and religious private).
I cant pretend to speak on any other areas of the country except for where I have lived and currently live.
I wouldn't ever claim the Deep South is well integrated.
