Don’t the blacks rule this country?? Why are they fighting each other......same a Chicago.
Tribalism
There are various tribes of black South Africans. While all are black, there are Zulus, Xhosa, Sotho, and a number of other groups, who fight each other.
As others have pointed out, it's mostly tribalism. It's also genetic; these people rioted against Nigerian immigrants would would want to set up shop there and bring some diversity.
The oldest human mtDNA (mother's side) is haplogroup L. It split into L0 and L1-L6. L1-L6 kept diversifying, more or less. Non-africans trace back to L3. L0 did not diversify except into sub-clades and is heavily represented in South Africa.
This is clearly racist, but also science.
Black Lies Matter…just blacks blacking…tribal warfare revisited…
