If you're going to criticise the "colonial powers", then you MUST criticise those who not only at the SAME time, but BEFORE and AFTER, actually facilitated all of it. Without those Black African others, the "colonial powers" would never been involved in any way. It wouldn't have even occurred to them. The "colonial powers" DIDN'T enslave them, Black Africans did. Perhaps all that should be taught as part of Black history.
A seven year old girl killed in Chicago, along with an eight year old girl in Atlanta. Bet they feel proud.
