These are the same accusations made among world leaders, human rights organizations, the UN, and the World Court. We should be free to make these accusations here on HN too.
This is a strong accusation, but it has the evidence behind it. The most recent of which is a report published at the UN Human Rights Council[1], but also the case filed at the World Court by South Africa in December with addenda added in March[2]. The evidence for this claim is both public, overwhelming, and has been filed at the world’s highest court.
All that said, I actually didn’t make the claim here—though I have elsewhere—I merely said we should be open to the possibility that this is the case.
