Thanks for providing your source. However we are not "forced" to speculate as there is no need to speculate period. The evidence is obvious, clear, and simple. There is little Islamic terrorism happening in Canada. Muslims do not pose a significant risk. The only substantial plot was reported to police by Muslims before it ever happened. 

Why is it up to Muslim columnists to defend themselves for actions that have nothing to do with them? Are you also demanding that Québécois columnists, or white columnists, or student columnists defend themselves from the actions of Bissonette?

You are not criticizing extremists. You are asking all Muslims to prove their allegiance and are considering them extremist if they don't. It's fear mongering and paranoid.
