"The reason anti-jihadists are trying to ban sharia is to avoid having U.S. judges cite it as in any way authoritative—which is precisely what Muslim supremacists want to see happen. Inspired as they are by the orthodox tenets of their religion, they believe... that the Quran and the Sunnah—the sources of sharia—are the only legitimate sources of sovereignty on earth. Everything else, including the U.S. Constitution and the will of the people, is a blasphemous usurpation of divine authority.
Knowing what we do of how Islam advances its power, slipping a pseudopod in through every gap that presents itself, then claiming that its grip is inviolable and irrevocable, it's essential that those of us who reject the Muslim claim to universal sovereignty slam every door tight against its legitimization."
