Let's write to Congress (www.congress.org):
Dear Representative:
Sharia enforces/codifies Islam, a supremacist religion, thus it is the imposition and enforcement of one religion on everyone. That is exactly what the Establishment Clause (First Amendment prohibition against government establishment of religion) is meant to prevent, the governmental establishment of one religion over any other. (It was originally meant to stop a Christian domination from being imposed over any other, but it also applies to all religions.) The U.S. Government is thus prevented from legally enforcing Catholic dogmas (e.g., forcing people to attend church on Sunday) or Hindu dogmas (e.g., forcing people to place incense/food in front of Hindu gods) or Jehovah Witness dogmas (e.g., requiring a certain amount of door-to-door witnessing), etc., etc. Under U.S. law, Muslims have every right to believe how they wish, but because our Constitution guarantees equality they have no right to privilege or plunder or imposition of Islam/Sharia onto others.
