It seems to me, as a non-PHD scholar, the solution to avoiding Muslim terror in Australia, is simple. 2-steps
1/ Close the door, 100% not 1 more, zilch, no family reunions, none returning from their shitholes.
2/ Those Muslims here, they put a foot wrong, either terrorism, subversion, incitement, preaching, sprouting their schieze on TV, come down on them so hard, deport them, and their whole extended family.
