What makes you black? Who defines and decides what constitute blackness? Blackness is a multitude of different peoples representing same historic people. This was, and continues to be historical reality in Africa, since ancient times. From Cape to Cairo, Morocco to Madagascar.
A politically inspired descriptive of ‘sub Saharan’ Africa, and African, is nothing but a recent racist neocolonial invention to perputate a neocolonial agenda. Sahara desert itself is a geographic phenomenon (climatic condition) not only unique to Africa. That part of Africa is never a natural barrier for people’s movement (migration and immigration), then or now.
