When we import hundreds of thousands of Muslims, many of which are extremists, of course that is more of a threat than importing hundreds of thousands of Philippinos or Vietnamese. It doesn't mean they all are, but the fact we seem unable or unwilling to distinguish between extremist islamists and 'normal" Muslims, and accept them all,  means we will get both, so yes, they are more of a threat than other groups.

Create a screening system that will accept the "normal" Muslims and screen out the extremists (Leitch's  Canadian values test), the problem disappears.

As a woman, yes I do have clear ideas about what I consider threatening. We've built a good society for women in the west, I don't want to jeopardize it. If that makes me a bigot, so be it.
