Why can't all Africans form a homogenous group as Europeans have been able to? It seems there is this problem with Sub-Saharan Africans claiming North African and Egyptian achievements the same way that all Europeans are 'white' and white people can sort of claim European achievements. It seems that Sub-Saharan Africans need to form this group at the bottom by themselves.
There is this exhibition at South Bank at the moment about black achievements and they are trying to include Egyptian pyramids in the discussion etc.
How do Egyptians and Arabs generally feel about Sub-Saharan Africans? Are they happy to embrace them?

Thanks
