He's trolling but, I understand what he's trying to say.
Ultimately, Blacks assisted in selling other Africans off into slavery because we foolishly fought against one another over tribal differences and didn't see each other as one racial group. Mistake #1. Blacks chose to live as slaves rather than burning the country to the ground. Some blacks did it (Seminoles, Haitians, Maroons, Nat Turner, Denmark Vesey) but, they all should have. Mistake #2. Blacks on the continent still allowed non-Africans to employ divisive tactics to get easy access to their resources and keep their countries in a perpetual state of instability and conflict. With a rewinding door of African elites being cool with it as long as they got money from Western organizations. Even now they're allowing China to exploit them when they could achieve the same growth by educating their workforce and bringing them back afterward. Mistake #3.
I feel like 100 years from now we all be dead and Africa will still be fukked up.
