Via Think Progress:
If you visit the Think Progress post on this, you'll note that the author cites Article IV of the U.S. Constitution as a refutation of Cain's Islamophobia. Here is that portion, with their emphasis on the last sentence:
The Senators and Representatives before mentioned, and the Members of the several State Legislatures, and all executive and judicial Officers, both of the United States and of the several States, shall be bound by Oath or Affirmation, to support this Constitution; but no religious test shall ever be required as a qualification to any office or public trust under the United States.The problem that Think Progress and anyone else runs into when they cite the Constitution to support Sharia Law is the political nature of Islam. Once that is understood, Sharia Law is no longer a First Amendment issue or an Article IV issue. It's an Article VI issue:
This Constitution, and the Laws of the United States which shall be made in Pursuance thereof; and all Treaties made, or which shall be made, under the Authority of the United States, shall be the supreme Law of the Land; and the Judges in every State shall be bound thereby, any Thing in the Constitution or Laws of any State to the Contrary notwithstanding.Sharia Law is designed to be the supreme law of any land in which it is implemented. That's the problem the liberals have in defending it.
