SA has big time problems with illegals. The blacks there don’t want to share what the white people built in SA with their fellow Africans.

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.
True story: about 10 years ago we went to Kenya to visit national parks. Our guide was "James" and he was great. He told us he was a Christian...which surprised me. On one of our long drives (it's a big country) I got to talk to him at length. At one point he got onto the subject of Somalis (Kenya and Somalia share a border). He went on to tell me how huge a problem illegal Somalis were in Kenya. They commit every imaginable type of crime...including terrorism. He absolutely hated them!
