It’s the not wanting to be associated with Africans or of being African descent, not whether or not we discovered Africa first.
How?
If anything this is just saying that "African descent" is not factual,and that we are of black descent period. Because we don't know where the hell we descended from first,all we know is that black people existed first and touched down everywhre first. So called africans may be of american descent if you want to get particular.
But the entire world was ours originally.
Plus your comment was phony as hell,in the sense that you are acting as though AA's are the ones who are doing all the "rejecting". If anything we are disrespectful by being indifferent to ALL of our ancestors who may have had different cultures,choosing to focus more on Egyptians and The Moors etc. But to act like AA's aren't the most rejected by other melinated people GLOBALLY is phony. Difference is we get bashed,as indifference isn't good enough. Then many of them latch on to the "cool" aspects and offerings of AA's. So correct your thinking and realize if anything this is taking away seperation of blacks,and should unite us all. If you understand what seperates us are all constructs created by us and then the white man later on.
