"The toxic anti-Muslim rhetoric south of the border has spread north, unvetted, through all firewalls."

What "toxic anti-Muslim rhetoric"? The attempt to improve vetting from 7 countries in the middle east and the ensuing hysteria and agenda?

Muslims are far safer in the U.S. than they are in Canada. Try dealing with it as a Canadian problem and see if that helps.
