Discuss the level of brutality in human beings, and the differences in levels of nastiness between Southern Africa and other regions.
Human beings are and will always be very nasty creatures. You and I are members of that club. The point I have been trying to make, which evidently you do not want to acknowledge, is that they were significantly less nasty in southern Africa, than elsewhere. You keep throwing up numbers of dead people that obviously exceed the total populations in the geographical areas you identified and that were alive at the time. Kinda makes the epithet you accorded to me as more appropriate to yourself.
