The Xhosa are a Bantu people, and thus no more “native” to South Africa than white Afrikaners. The true natives of SA are !Kung Bushmen who were displaced by both Bantus and later by Afrikaners. So Xhosa “nativism” and “xenophobia” (which incidentally applies to Zulus as well) is no morally different from Apartheid. It’s all about whose ox is being gored.
I expect Bono and Co. to re-record “I Ain’t Gonna Play Sun City.”
