Nor is it mention that: “In Charleston, South Carolina in 1860 125 free Negroes owned slaves; six of them owning 10 or more. Of the $1.5 million in taxable property owned by free Negroes in Charleston, more than $300,000 represented slave holdings. In North Carolina 69 free Negroes were slave owners.”
You’re right. Also, there were thousands of black slave owners in New Orleans alone and there were black slave breeders who sold their own children into slavery. One of the first slaves to be freed became a slave breeder.
