Absurd (and non-existent) problem indeed! Oh, and they don't have to speak out, but they do anyway. There's no chance of Canada actually coming under the rule of Shariah, seeing as how the Muslims there are a fairly small minority that are happy to go about their lives. People just don't like them, and use this sort of thing to get everybody afraid of having their hands chopped off when that's never really going to happen.
