How many people say this? And what do they mean by a "sharia court?" Because folks like yourself will pick out the most heinous parts of the Quran and assume that "sharia court" includes that, but if I do the same regarding the Old Testament, I'm a bad person apparently.
So I need more details.
In any case, who cares if some religious people want to enforce their religion onto everyone else? Just don't let them do that. In America, we have this thing called the constitution. If we stick with it, we wont have a problem with sharia law, or jewish law, or buddhist law.
One of you will end up here next!
Municipalities have had zoning restrictions for hundreds of years. Wheaton Illinois may never have a bar that serves liquer. Not because it is illegal but because zoning ordinances prohibit a bar from openng within a predetermined distance of a church or school. It just so happens there are so many churches and schools that there is literally no physical location to legally open a bar. Perhaps Kennesaw has an ordinance that will not allow a place of worship within a perdetermined distance to a gun store or range and they are just all out of space.
