I think you are generally right due to the scar caused by apartheid. There is actually a prominent white soccer player that is married to a black woman. His name is Mathew Booth.
Well, it certainly looks as if she's washed the mental baggage of apartheid from her mind, judging from these pics.
It will probably get deleted or scratched. lol. Remember her kissing scene with Will Smith in Hancock got deleted and there was suppose to be a sex scene between her and Idris Elba in Prometheus but it seems the scene got thrown out all together.(Surprisingly A lot of white guys that are sci-fi fans were bummed about that.)
