Why?
No it's not. It's caused by muslims themselves. You don't see Buddhists which are larger in number in Australia having the same problems as muslins as Buddhists don't cause anywhere as much trouble.
The problem may not be you. As you or another poster believed, it is 10% of muslims giving the other 90% a bad name.
The challenge for you and the other 90% of muslims is to reign in that 10%. If fellow muslims won't, then Australia will be forced to act against the religion as a whole.
