"When the Muslims have the majority in this country..." Please tell me you're kidding...
America is a Christian Nation, and will be until the End of the Age, denoted as "A.D." After that, you won't have to worry about Muslims, because they'll all have eternity to contemplate their bad judgement, and won't be bothering anybody.
And what about Confucianism? Kung Fu Tze was a kind of Peter Drucker of his day, with a goal of improving the performance of the Chinese bureaucracy. Many of our nominally Christian bureaucrats would benefit from a reading of the analects.
