The point is Africa is Africa now, and let us be adult about this, in many nations there are hundreds of thousands who dont even know their ancestral language only the White mans forced language. For thirty years I have heard folks say national borders were forced on Africans well if that is the case an there is a spirit among the grassroots to, as you say go back to multi ethnic and multi cultural, why is there such a recalcitrance to that right now in the ipad age, 40 years after liberation?. For one...one would assume if there was the former sentiment as you say Pan Africanism would not be something we are discussing as a wonderful idea in some glorious future, but instead something we could look back at and count the achievements of, as well as be discussing how much we as Africans in the diaspora should be trading and investing in a Pan African continent of unified people, unified without uniformity.
