I know hes being all extra about it cause he's
@The White Man, but it did actually happen. Though usually this is a point raised to deflect from the inhumanity of antebellum slavery. Of course, African slavery is a little more complex than that.
For instance, the slave trade in east and north East africa was done by "Africans", but these were mostly Arabs and half-Arabs that migrated and set up shop in East Africa. Ironically these were also thefirst "Africans" to let Europeans set up slave trading ports. They even had a little segregation set up that was active from mombasa to madagascar that favored these "Arab" Africans(and their c0ons) over the black ones. It was a big issue once the Euros left and gave places like Zanzibar independence.
Additionally, if you read many of the brittish and french field journals/ethnographies from 1700s and 1800s, what whites encountered when they got to the continent was that many parts of Africa had a system resembling indentured servitude, moreso than slavery. So its a bit deceptive to call it such. In many of these cases a "slave" would be garunteed freedom after xyz years and even receive land on the plot he previously tended to.
Dont get me wrong though, there was definitely what we'd call traditional slavery in central and north western Africa(which creeped more south as tribes like Arabized tribes like Hausa migrated). However, the severity and cruelty of this slavery was nothing like the American, Carribean, or Brazilian kind which turned the offspring of slaves into slaves themselves and often times worked these slaves to death, with goal of just replacing them like an object.
As an extra point, there were many many many many many black African ethnicities that fought and hated the practice of slavery. I know
