yes.
In many cases like that of Tippu Tip falls into a category that we might call the consequences of forced cultural assimilation via White (or Red) Arab Conquest over Africa. Tippu Tip s father was a White (or Red) Arab slave raider, his mother an unmixed African slave. Tip was born out of violence, the rape of an African woman. It is said that Tip, a "mulatto", was merciless to Africans. There may have been other "bi-racial" individuals that were no different.Also,some of the black Afrikans that were in Arabia who called themselves Arabs tried to participate in the enlsavment themselves,the odd thing is is the fact that many of them were beaten and sold into slavery as if they were from Ethiopia,when they only had a connection to that land through blood and not affiliation in terms of self-definition.I read an article earlier today about Arabs in S.Arabia discriminating against black Arabs and telling them that they are Negroes instead of Arabs like they want to be,or actually are,depending on your perception.Lastly,many empires such as the Ottoman Empire and the Persian Empire profited,but the Arabs remain the focus since they have the most Afrikan ancestry(according to modern "scientist" )than many of the other groups.
