I'll comment on a part of this thoughtful post.

You said:
"Afrikan unity does not mean we become one homogenous mass. Afrikan unity is more feasible when all cultural conglomerates from the ones who number in the hundreds to the ones numbered in the tens of millions have their own space in which they can be what they are."

* This is correct.

In order for us to be fair to ourselves and others, we have to appreciate our historical and present relationships with diverse people. We have to understand how we view each other to ensure that we do not allow poor understandings to be the catalyst for abuses and genocide.

Sure, we have to leave different people to their own culture, while ensuring that THEIR cultural priorities do not negatively impact on us. Quite often people work out their own life story through interacting with others who are different to them. Our stories are interconnected.

If people only identify with the aspect of their evolution that changed outside of Africa, or as a result of 'race mixing', then they are susceptible to inferior and superior complexes that can be a danger to us all. It is too easy to manipulate people who are so narrowly defined.
