First off, the original slave traders were slave RAIDERS who went around kidnapping people. all these Great Replacement Blacks (Israelites, ADOS,Kemetics etc) seem to forget that.
The slave TRADE of POW’s came about as a result of White people forcing these kingdoms on the flank to partake. Just like Gaspar Yanga and many other enslaved Africans did in the Americas.
Whats more, what do you say to the “African” that himself was enslaved and never took part in the slave trade? Uncles and cousins who were never made the trip but hold the same DNA as you? imagine looking him in the face and telling him “you sold me!”
