There's probably more to the 1950s story that you're conveniently leaving out BUT even if it were all true then it still doesn't justify the South African government's actions now. You're actually talking about something that happened 60 plus years ago. Few if any adults responsible for or took part in it are alive now. It's still punishing the children or grandchildren for their father's sins. It's vengeance, which never makes for good policy. You don't build a nation of revenge and racial hatred. Do not justify their genocide on innocent whites who are already discriminated against.

You've failed to mention the tortures and slaughters of tens of thousands of farmers' families and other white South Africans that have been going on for over two decadeds. That's genocide! Do they have a right to stab 6 month old babies to death? Is that justified? Do they have the right to torture elderly couples with blow torches or chop up entire families with machetes? That is what you're defending! There's no excuses for those savages.
