I think that everyone's thoughts are with the families of those killed and injured in this horrific attack.

And the columnist is right that care must be taken not to demonize any group and that doing so brings with it the risk of violence being perpetrated on those demonized.

At the same time, the columnist ignores the fact that there is a clash of values between the views of some followers of Islam and many others in society. For example,  I hope that the great majority of Canadians agrees that it would be wrong to throw homosexuals off of the roof of Place Ville Marie because of their sexual orientation. Yet some adherents of Islam see no problem in as they see no problem in killing young women for the crime of dancing.

So the solution cannot be, as the columnist seems to suggest, refraining from a vigorous defence of secular values out of a fear of offending the sensibilities of those who hold extremist views.
