I've been racially abused on the footy field and in classrooms (for being Aboriginal). There was a time I got all sad, emotional and distressed about it.
After a while, I learnt 'these b*stards know I am better'. From then on, the attitude was to be ruthless and ensure I won no matter what. Then after it, shake their hands, smile, and be classy. Because no matter what those b*stards say or do, they will never ever beat me.
I honestly wish more Indigenous sports men took some perspective in this: you are racially abused as a form of sledging. It is because the opposition knows it is the last thing they have over you to put you off your game. So read between the lines... the fact they are bringing up race means they are inadvertently acknowledging you are the superior player. So don't put the head down and cry nor throw punches... tear them apart on the field, and then rub it in by being respectful to them after you've humiliated them on the field.
