Lack of moral courage by other spectators at club games allows sideline abusers to get away with their abhorrent behaviour.
The All Blacks are as good a reflection as any of our multicultural society. Their composition, and their outstanding level of success, should long ago have made displays of racism in rugby nonsensical. Yet last weekend's Canterbury club final was marred by racial abuse hurled from the sideline at Christchurch's Fijian winger, Sake Aca. Eventually, and understandably, he was removed from the field in tears.
It would be of some comfort, but still no excuse, if this had been an isolated incident. Clearly, however, that is not totally the case. Earlier in the season, allegations of racist taunting were made after a country game between a Mid-Canterbury side, Hampstead, and North Canterbury's Saracens.
That prompted a Southbridge player, Manumanuniliwa Peni, to say he had been subjected to frequent abuse while playing for Dan Carter's club.
This type of behaviour is usually associated with the likes of English football, not rugby in New Zealand. But if racist abuse was once standard fare at stadiums such as Stamford Bridge and Old Trafford, the eyes and ears of an increased number of stewards, security personnel and CCTV, and the presence of black players, have gone a long way towards eliminating the problem. Now, racist incidents are most likely to take place when football supporters are away from stadiums or at youth matches.
