That deeply offends me sir. I am not a racist, and I actually defend many people whom racist remarks are made towards. I hear racism every day in my community, far worse than anything Joey has said, I hear jokes made about racism at my football club, in which the Fijians and Tongans outnumber the white people by far, and none of them leave. I am good friends with all of them. I have withstood many remarks made about my non-religious beliefs, and I have been offended by them often. I changed my whole lifestyle about 3 1/2 years ago, when my friend was killed, by an aboriginal, who was also my friend. I used to have a 'f**k off we're full' attitude towards immigrants and indigenous people, but I learnt tolerance after that. In fact I believe there are no races, just the human race, I do not call anyone black or white or yellow, we are all just human, and I believe there should be no countries, as they are only divisive.
So to you I say, calling me a racist is deeply offensive and disgusting, good humoured or not, and I will not stand for it. However, I will not just get up and leave and not return, but face up to it.
