I look at how Africans interact with other races...namely Whites in 2016 and I don't think the behavior diverges far from when the first Portuguese sailors arrived.
I look at how Ethiopian is able to nation build while a place like Nigeria is in disarray except Igboland and I think the same was generally true back then.
Really, I think in every aspect....Africans haven't changed much and to see how and why things happened, we only need to look at how they act in 2016 and map it onto scenarios of the past.
Quite frankly, I am not hopeful after this revelation. The need for White acceptance and ethnic tension is biological. I hate to say it but its the only explanation for the shyt I see.
