I don't think anyone is afraid to think about it. In order to do so you would have to look at what the conditions were prior to Christianity and the diaspora.

in other words is Africa had been left to it's own disposition...

I don't think it would have been possible for Africa to remain free unless there had been a uniting of the nations, tribes etc. there are too many minerals and valuable resources. carpet baggers would have come with schemes and it would have been on either way.

now the potential for Africa to be the greatest nation in this age was there. just look at the brilliant african minds spead all about in many fields. the revenue from the resources could have helped 'tame' the jungle and set agriculture to benefit the continent.

there was great potential. ****(as a sideline what got us in that weak of a state)? to be steamed rolled by so called christians, arab slavers and the likes***
