Well of course there have always been tribal conflicts and so forth, to one extent or another. Your post seems to imply that someone was denying this, that people are saying that everything was 100% hunky-dory perfect before the whiteman arrived. I think the vast majority of conscious Africans are well aware that things were never ever 100% hunky-dory perfect anytime, anywhere.
But as you yourself acknowledge, the arrival of Europeans made things much, much, much worse.
At the risk of 'putting words in your mouth' or whatever, I have to ask what is the point of this post really, did anyone on here ever suggest that things were absolutely 100% perfect anywhere on earth before the arrival of the europeans?
