I'm fully aware that Aboriginal culture and tradition have been disgraced by the colonisers. What I disagree with is this idea of collective guilt for ALL Australians.
The fact is that if the Europeans hadn't colonised Australia, another country would have. It was an inevitability. I'm not saying that the colonisation was right, I fully understand that Australia was the Aboriginal people's land, but it was going to happen regardless of which country did it.
If you define yourself as Australian, you must take on the responsibility that follows. You do not have to call yourself Australian. You can just be yourself, you are a child of the universe, you belong to yourself alone.
