The largest blame falls on the multiculturalists, who look the other way at this cr**. My understanding is that the Aussies have been putting up with a lot of hostility and outright criminal activity, so I'm not surprised the pot is starting to boil over.
In effect, the day is coming when the phrase, " You wanted a war, well now you got one. " is going to be heard by those Muslims who refuse to respect the society in which they live. Then we'll hear the typical, " we can't understand why they're persecuting us poor harmless Muslims. Its (racism/religious bigotry/right wingers) who are getting out of hand. "
You are exactly right. This is the beginning of a clash of epic proportions. Unfortunately, the apathy of the silent muslim "majority", will allow the islamofacists to push the west away from its hyper-enlightened state of mind and revert to the law of the jungle.
