'Isn't it funny that so many people in this country keep insisting that it is their 'right' to insult and degrade'

I'm more worried about the people who think it's their 'right' to never be offended.

' ethnic minorities, victims of crime, people with disabilities and anyone else who can't fight back.'

They can fight back if they want to. They often do too. Why should they be excluded form jokes. How patronising. So you don't think they can laugh at their own idiosyncrasies. Disabled people have no sense of humour? Only able people with a political career can be mocked, or laugh at themselves? That's just stupid.

'Then we all wonder why the rest of the world thinks Australians are a bunch of racist louts.'

No more so than your average Texan. Or German. Or Chinese. Why do you care so much what 'the world' thinks. Do you have a small weiner?

' I guess the joke is on all of us.'
Maybe just on you

Rule Number 1. Australian Racists are the only ones that are allowed to declare when and when racism happens because they are the experts.
