Schools are overlooking? OH NO---they aren't overlooking---they are trying rewrite history. There is a massive agenda to hide that BLACKS owned slaves even here...............along with another agenda that many blacks were actually wealthy enough to own slaves. Then you have who were worst slave owners overall, who sold their family into slavery, and who started slavery here. These issues would affect white guilt and claims of victimhood.
No there isn't any massive agenda...
Free blacks bought their own families back when they could.
