“We aren’t leaving” say the white groups that went touring “white genocide” across the USA a few years back. Fuck those actual racist shitheads. As a south African I would happily have them leave. Actually, if they want to feel persecuted, I will volunteer to persecute them. I am white, so I can offer a “superior” persecution.

Incorrect. If all black people were killed, then discrimination would end. Your scenario involves Afrikaner corpses, which are white and therefore worth 10^N with N -> \infty of “the blacks”. Thus, you cannot trivially cancel 0 dead Afrikaners with anything except a similar number of Israelis.

Excuse me while I puke after typing that, but I live in SA.
