the whites mostly got that land through govt policy and outright racism so some policy redress to spread the wealth is probably not a bad idea. If the land was brought by the govt at a reasonable price, and voluntarily then that is OK.
however hastening slowly may have been a better option. train the people who the farms were given to, to work the farms properly. this may have been better than parachuting someone into a productive farm with bugger all training, support and probably limited money.
BTW South African farmers aren't the only ones getting offed. the murder rate in SA makes it 9th on the list of murder rates in the world. 37 per 100,000. as a comparison Australia is at 1.2 per 100,000, Japan 0.44 per 100,000, England 1.37 and the US which is very poor among Western countries at 5.4 / 100,000
It's just not a very safe place really, farmer or not.
