I agree Richo, abusing someone becuase of their race is a very serious crime, regardless of the person. Just cos Gibbs has a bit of black blood in him, it doesnt let him racially abuse people. While im fairly sure thats not what you were implying, regardless whether it was Gibbs, Ntini, Amla, or a man who is 1/4 white, 1/4 Black, 1/4 middle eastern and 1/4 Asian, racial abuse is not acceptable, especially in a country with South Africa's history; not that Australia is a beacon of moral guidance.
While i dont really agree with the quota system in RSA cricket, its only really been an issue once or twice... Ontong beng selected ahead of Rudolph a few years back, but today, Prince (who was unfortnate not to be MOS against India) Gibbs and Ntini all deserve to be select in the RSA First 11. I wouldnt take what Pietersen does as a "stand against reserve racism", the guy is a f**kwit.
Honestly, i find it strange that something like this, despite its seriousness and the repercussions it will have, is SUCH a big deal, when Zimbabwe and Zimbabwean cricket is a mess, ran by f**kwits and idiots.
