I don't care what religion they are. They should come through the proper channels and we must ensure that we don't allow entry to those who have a fanatical bent religious or otherwise. And it's' obvious to a drover's dog who they are.
And this should apply to those who overstay their visa as well as those who enter this country illegally (that's illegal as defined by common sense and not by the legal beagles who define it to suit their own agenda so they can circumvent the Government's immigration policy)
