Australia has now been listed on the "Enemies of the Internet" list, along side Iran, China and several other countries who's Governments supress the Freedoms of their populations.
As for Australians being racist, I think you'll find the vocal minority that you've encountered are fairly identical to the vocal minority I've encountered from: Africa, America, China, Japan, New Zealand, Australia, Germany, Iran and any other country with Internet access. The simple fact of the matter is its not any one nation or peoples propergating racism; you'll find racism everywhere if you look hard enough. If you honestly think Australia as a nation - or any nation as a whole - is racist and promotes racism or discrimination then you've listened to the limited, bias media reports which attempt to drum up controversy of any kind to sell more news papers or recieve more internet traffic to gain more money from their advertising deals, such as the 'Hey Hey Its Saturday' Black-face 'scandal'.
