SIGH, the real reason why is cuz white people want AFRICA. They want the land, the resources like gold, oil and other minerals etc and anytime black people in AMERICA or anywhere else in this world trace their history and see how powerful nikkas was in AFRICA it gives them a sense of pride and appreciation for AFRICA thereby making it harder for nikkas to let go of the land, resources, gold, oil, minerals etc and giving nikkas in AMerica a better sense of self.
White folks want to rewrite our entire history to make us feel like we ain't shyt so we constantly take no pride in our selves and keep us in the mental slavery most of us stay in in AMERICA so we fight against each other and constantly have to rely on white folks to maintain. That's why.
