content: I've heard this before somewhere else. A landowning farmer had two groups of workers, the bushmen (i.e. one of the native peoples of the region, who look very different to the typical "african" black phenotype. The other were the typical black, zulu descendant phenotype. The gist was the browns were peaceful and got on well with their work, the only time the landowner had to check in on them was when they needed medical aid for a childbirth or someone got injured on the job or whatever. With the "blacks", they were constantly getting into fights and routinely chopping and stabbing each other, and they eventually ended up lynching on of their own for putting a curse on some food or something. It was a really interesting comment, I can't remember where I read it.
