And how exactly do you think that followers of Sharia Law would be able to "enact their own courts,  . .  police force," etc., for people who are not Islamic?  There is no way for that to happen in this country.  Note that many churches don't recognize same sex marriage. Yet it is the law of the land (one I agree with, not that anyone needs my permission).  Jim Minnery may not like it but he has no legal authority to ban it for everyone else.  Instead, he is free not to marry another guy, just as my RC neighbors are free to seek annulments rather than divorces (or to forego communion if they can't have their marriages dissolved according to the laws of their church) and my Islamic neighbors are free to follow Sharia law if that makes them happy.  Stop fear-mongering about something that is never going to happen.
