A lot of minority rich areas of the south don’t have enough economic base to support both blacks and hispanics vying for the same jobs unless it’s a city of medium size or better.
The scattered counties of Hispanic density tend to have intensive agriculture which hasn’t been a black minority dominated industry for decades.
I really don’t want to live around anyone whose culture likes incarceration, drug use & sale, gangs and other uncivilized behaviors. I don’t care what “color” they are. It is a free country...live where ever you want to live.
