“Very much like the left you are trying to generalize a topic”
You are the one who generalized it, with your claim “had white people not been willing to pay for slaves there wouldn’t have been a market”
Also be aware that due to the Napoleonic Code rules of inheritance in Louisiana, many children of slave/slaveowner parents (as “black” as say, Barack Obama, Louis Farrakan, or Jesse Jackson) inherited slaves themselves, upon their parents death. This accumulated to such a percentage by the time of the Civil War, that black slaveowners from Louisiana could field a Brigade on behalf of the Confederacy.
There were thousands of blacks who owned black slaves.
American Indians owned thousands of black slaves.
The first legal slave owner in American history (who established the legal precedent) was a black tobacco farmer in Virginia named Anthony Johnson.
North Carolina’s largest slave holder in 1860 was a black plantation owner named William Ellison.
Only a tiny percentage of American whites ever owned slaves - never more than 3% in any state, ever.
I generalized nothing
None of which has to do with the story of the last living slave from the last slave ship to come to the US
