I think it's because of people like you who condone this behaviour. I have seen it all through junior sport allowing these brats to get away with murder; kids throwing golf clubs, kicking golf bags; idiots like this fool, Shane Crawford assaulting people on the football field, etc etc!
The parents are too weak as are the sports officials, now I am done on this. It is not an ethnic thing Kol, now brush off the chip and move on!
