Although American blacks haven’t enslaved fellow blacks (they would if they could),they do the next best thing...shoot the hell out of each other! (Especially on weekends.)
Respectfully, untrue in the past.
“By 1830, there were 3,775 black (including mixed-race) slaveholders in the South who owned a total of 12,760 slaves; around 2 million in the south. [6] 80% of the black slaveholders were located in Louisiana, South Carolina, Virginia and Maryland.”
