All of this is really rather easy to debunk. Name one thing that he ever predicted correctly, then quote me the exact passage where he predicted it. You won't be able to because everything he said was nonsense. Stuff like "the 7 lean red cows will eat the green grass while the big blag warrior with the dung droppings runs over the red carpet" that means nothing except to people who try and make it fit after the fact. That wasn't a direct quote for those not well versed in the art of sarcasm, but it might as well have been.
Secondly, for the imagined predictions to happen there would have to be a will amongst white people to do so. There is none, except for a small group of insane people. Most people just want to get on with their lives and aren't preoccupied with BS.
Lastly, Afrikaner = Afrikaans speaking person of Dutch, German and French descent (loosely) that share a common history. Therefore Afrikaners = Boers, Boers = Afrikaners. The difference only exists in the mind of a tiny racist superstitious minority that believe that they were decedent from Israel. These people are brainwashed and delusional and hang out on forums like Stormfront where they tell each other how right and awesome they are while sharing disgusting images of people brutally murdered on farms for their own morbid and perverse curiosity while claiming that it proves their point.
So in summation, Sly21C, I wouldn't worry about this rubbish. It just isn't going to happen, much like the Uhuru when Madiba dies myth.
