Hate to say it but the Whites should leave South Africa.
I think they are leaving in droves. I know 2 that moved here about 1995. They told me that it was a nightmare living there. Their wives were afraid to close their eyes to wash their face in the shower. That was in a locked house with a wall all the way around it.
One of them told me BMW means break my windows. It was a joke but not really.
