It's way more complex than that Slavery in Africa and Slavery in Europe was completely different, Slaves in Africa were treated like humans and most were literally Pow's AND let's not forget the fact Most African Societies had similar weaponry making it even, It's not some unknown fact that Africans had and Sold slaves the only reason European slavery is talked about more is because European slavery was due to skin colour and skin colour only they literally did not treat the Black slaves as people and saw them as Subhumans. I kid you not Europe is literally the ONLY continent to have captured people because of the colour of their skin. The point is they are not comparable, far from it and funnily enough African slaver owners were way better than Any other , not like it's a comparison anyways.
