Atlas Shrugs has this whole story.

What is happening in South Africa against the White population is unspeakable. Savage. And no one will speak of it.

Facebook jihad on South African whites: Ahmed El Saud @ Chris: we will do the job for your people. We will kill the whites at a agreed price per head. We deliver all heads and expect raw cash, gold or diamonds as payment. Baby heads are same as grown up's in price. We will give you instructions on how to arrange the payment and the terms and conditions. Do not worry now. We provide also body guards if you are in need. Just speak out. We can bring in planes and do it with poison spray but your people must be out of the area.
