In South Africa there is a lot more going on than just white farmers having their land illegally seized. They are also being murdered in great numbers while the corrupt, racist government there either plays a hand in it or just ignores it.
Widespread oppression of white people in Sourh Africa is an actual thing, unlike the imagined "widespread oppresion" of black people in America.
Yeah, reparations for those farmers in South Africa would actually be justified unlike the idea of reparations for black people living in America today who have never experienced slavery themselves or had their land wrongly taken away from them with no compensation.
