Afrocentric are historical revisionists. Cheikh Anta Diop was their Guru...,,,His theories have largely been
exposed by other historians and now DNA (Niger Congo people have nothing to do with civilisations like Egypt).
On the issue of Slavery, I think it is a very emotive subject and hard for them
to be academically objective. They blame Whites and Arabs for selling and exporting, however the truth is a little more in the middle-many African ethnic groups sold their captured enemies. Such a fact is hard to take if you are trying to spread the propaganda of “ African civilisation were united before the Whites and Arabs came”.
Europeans also enslaved each other too, hence the name “slavs” coming about. Thomas Sowell, a black economist wrote a great book on this subject regarding slavery, showing that it is universal to human nature. It surprised me for sure.
