In this country, religious laws and customs are always subordinate to the law of the land. Reasonable exceptions have been made in the courts for certain religious practices, but always on a case by case basis and never in situations where the public was put at risk.

We need not worry about Sharia. What we should worry about is the paranoia of those who would limit the freedom of religion of those of whom they disapprove. When, in the history of this nation, has that ever worked out well?
