Does he cite any statistics?
It begins with clips of news reports of murdered farmers interspersed with footage of Malema's opposition party singing the old ANC 'shoot the Boer' revolutionary song. Looks bad, but is far from convincing evidence of genocide. Also, the clip of Ramaphosa urging 'a return to militancy'... in what context was he calling for such? The way it was edited suggests it was South Africa's president encouraging targeted killings, but was it?
Not sure if there would be any reliable statistics about this sort of thing? I found the comments on the video Beau posted interesting - many testimonies from white South Africans (and even one black South African) who seem to support that there's something going on (i.e. specifically anti-White violence/murder against the Boer farmers).
It's hard to get a read on the actual situation. On the one hand, you can't just see it through the lens of the Western culture war and MAGA. On the other hand, we should keep in mind that libtards (including libtards in SA) are cognitively incapable of computing anything other than either "there is no issue, nothing to see" or "if there is an issue, it's justified because of the apartheid past". So it's an ideological minefield, and the real situation is probably more complex.
