The beginning of the end was when they let that commie shitbird Mandela out of prison. They should have executed him.
Mandela was bad news but the whites were largely left alone during his rule; he understood what South Africa’s future looked like without them (it was just to the north of them, in Zimbabwe), and begged them not to leave. The fact that so many did stay at that time would lead me to believe he was sincere in that.
