Why would you kick a 71-years-old man? In the back no less. Is this supposed to prove something?
IMO, white people should quit putting money into South Africa anyway so long as they have their "reverse-Apartheid" government running the country into the ground and taking an official government stance that whites should pay for the ineptitude of the blacks running the place.
And before anyone yelps, I would ask them to recall the amount of pressure put on the white South African government when it was the other way around. If it's not okay, it's not okay, regardless who is doing it.
