Islam is not a religion as westerners think of it. It is a political ideology as well as a religious belief system. The political nature of it is antithetical to, and destructive of, any other government, including the U.S. Constitution. It is a totalitarian ideology that requires world domination. Moderating influences of any consequence to changing Islam have come not from within Islam, but from the Western world. Turkey is one example, and even that is under threat from an Islamist Prime Minister and ruling party.
Newt Gingrich is correct in requiring his appointees to renounce sharia. That is a convenient dividing line. Whether or not the individual will be sincere in that renunciation, given the Muslim practice of lying for the cause (Taqiyyah) is open to question, but at least it marks a line and sets a standard that political loyalty to the U.S. supersedes any other political loyalty, including to Allah, the Umma, or the Caliphate.
A statistical analysis of Muslim employees in the U.S. Government is long overdue as well, just as it would be for any violent and totalitarian group in the U.S.
