Double standards? To my knowledge there's never been an act of terrorism committed by a Muslim in Canada. Yet you speak as if it's an imminent threat. That's because as opposed to non-Muslims, you consider Muslims in general a threat. 

But let's not mince words. It's not a double standard you evince, it's bigotry. And like most people under that negative influence, you've rationalized it to yourself. Even when people point out clear examples of it in what you think and say, you'll deny it.
