We accommodate Mennonites and Hutterites  in Western Canada. Public school Teachers have to go to the colonies to teach. Mennonite men will not serve in the Canadian military even if drafted due to their religious beliefs. What message does that send to society?  Violent Christians such as Timothy McVeigh bomb government buildings in the US killing children, and Christian activists threaten and occasionally do shoot doctors performing abortions. No apologies from the Christian community for these nut bars... Zionist settler extremists in Israel assassinated Yitzak Rabine for pursuing peace on the West Bank.  Point is Islam is certainly not the only Abrahamic religion with violent and extreme members who twist faith into something awful. 

It would seem to an outside observer that the "guise of religious freedom" in Canada  is somehow only to be applied to accommodate Christians and Jews and not others.
