South Africa, as a post-apartheid democracy, is years younger than I am. And while legal oppression of the African population (as well as the sizable Indian and mixed population) has been overturned, in practice white South Africans still enjoy many legal and social benefits that minorities do not.
I don't think you can paint either side as the good guys in this; when you have politicians on one side saying that the opponent needs to be exterminated like Hitler did to the Jews, and politicians on the other side saying they are a bunch of monkeys (and other racial slurs) who just live in trash and want free hand outs (while continuing social programs and norms that benefit the white community at the cost of the African community, or refusing to recognize that the land WAS "legally" stolen during appartheid and should belong to Africans, making the tension even worse)... fuck both sides.
For your question pr, why it's not being discussed...
Appartheid has not returned; there were good guys and there were bad guys during appartheid, and that division was extremely clear. This is bad guy vs bad guy, why would we want to join either?
Edit: So watched the video, and realised it only wants to talk about how one side is the villain without showing how terrible the other side has been as well. Surprise, surprise.
