There are many religious societies that have co-existed in Canada's borders over the years.  Mennonites come to my mind first.  They are a pacifist society, stick to themselves:  old order Mennonites still live without electricity and indoor plumbing.  Why are there no radical Mennonites?  Because they are taught pacifism from an early age.  Perhaps it is time the Muslim religion took the Mennonites as an example of how to live in western society and still maintaine their religious identity.  There are plenty of other religious groups that live peacefully amongst us.  The problem is not within our western society, it is within the Islamic society.  Until Islam adapts to western values, there will be no peace.
