On balance, reading back through the 'discussion', I think you are probably not !
wrt Africa, the initial colonial conquests of the European powers imposed artificial boundaries, and alien social concepts, on the established cultures. They were no more violent to each others' 'tribes' than their new masters had been to each other during the preceding centuries of European history, whether in the name of geographical, political, or religious causes.
Once the imperial powers became established, they started eyeing up each others foreign territories, and so we exported European wars and prejudices to the continent, and as these conflicts, particularly WWI, progressed, the political map was realigned to match the prevalent European balance of power.
It is a quite reasonable assertion, for instance, that the problems of the Hutus and Tutsis are directly linked to European, particularly Belgian, meddling. Similarly, the tensions in RSA, Namibia, and Zimbabwe, are inextricably linked to the concept of white ( European ) racial supremacy.
