Cant we all get along? Why all the racisim in South Africa?

Here in America we Celebrate Martin luther King and all you South Africans Are hating each other and killing everyone why cant you be smart like us and just stop. Even in Yahoo answers you all fight like a bunch of children and ignorant bigots. The African Americans in this country cant understand you. And I am white married to A Black South African and we all did the work and freed all of our people but you stupids are still in the last century with all the racisim. You need a revolution.
