I am saddened by the horror that took place in the Mosque in Quebec, and I can't possibly imagine the anguish that has fallen upon the families of the victims.

Konrad-- you cite the horrific event that took place in 1989 in Montreal, but you left out a few facts: This tragedy was perpetrated by a young Muslim man named Gamil Rodriquez Liass Gharbi, the son of  an abusive, misogynist Algerian Muslim businessman named Rachid Liass Gharbi. 

Following the divorce of his parents, Gamil changed his name to include his Canadian mother's maiden name, and he became Marc Lepine.

Is this relevant? Perhaps.

Google it.
