I completely agree Super. If you are not willing to respect the laws of your country and are not willing to follow the democratic process to change those laws, than you should be forced to leave...actually you should be in jail for breaking the law.

But just because someone wants to live under Shariah Law doesn't mean that they will be violent or promote violence, and there's nothing in any Western countries consitution to say that they cannot vocally call for such a thing (how else would you get people to vote). So if someone is simply promoting the idea vocally I do not think they should be told to leave. It's undemocratic.
