Never had an issue with the statement that white people benefited apartheid. The issue is putting all people in the same basket. Take this paragraph in this article for instance:
"..just as most white South Africans of a certain generation will not admit that – either through our active and enthusiastic support or through our silence – almost all of us were complicit in perpetuating a crime against humanity: apartheid."
The word that really gripes me is that we were "complicit". One can argue semantics, but generally this implies active and voluntary support. And  "many" whites may not have actively fought apartheid due to fear of reprisals (a very very human trait when looking at our latest no confidence vote), yet its just not that simple to just condemn all (uhh sorry I mean most) white people.
