I lived in Corinth and the blacks in Memphis were some of the most prejudiced and desired whites dead almost universally. I served in the NG during the 1978 Fireman’s Riots and found the blacks to be some of the most dangerous and hateful people to be encountered. We had our Mid South Civil War shows the same weekend as the COGIC conventions and saw the same as you. If any enemy of the US were want to destroy Memphis they wouldn’t have to hit the city...all they would have to do is detonate a bomb nearby and the blacks in Memphis would destroy the city themselves.
Thank Martin Luther King for that.
Everywhere he spoke a riot followed.
