Suppose Yaser Bushnaq had obtained that citizenship in 1980, before certain laws were in place to deal with such matters. Would he then be an "American" or would he be, would he have always have been, someone who, while he had obtained American "citizenship" remained resolutely hostile to the political and legal institutions of this country, and hostile as well to the American Constitution, which in so many ways flatly contradicts both the letter (the Shari'a) and the spirit of Islam.
Can those who subscribe to, whose lives are suffused by, Islam ever be loyal citizens to Infidel nation-states, such as the United States, or Great Britain? I need to have explained how this is possible. If you claim to believe in the Qur'an, immutable and uncreated, as the literal Word of God, if you furthermore claim that the Hadith and the Sira (the Biography of Muhammad) correctly represent that central figure in Islam, that Exemplary Figure for All Time (uswa hasana, al-insan al-kamil), Muhammad, and that both Hadith and Sira serve as glosses on, that Word of God in the Qur'an, then how is it possible to offer one's allegiance to the Constitution of the United States, or to the "unwritten Constitution" of Great Britain, or to any state created of, by, and essentially for, Infidels? Not possible.
This circle cannot be squared. And that may explain why everyone stays far away from this subject. Too hot to handle. Too impossible to deal with. Too troubling. One of those Disagreeables that our Podsnaps put out of their minds. "I don't want to know about it, I don't choose to discuss it; I don't admit it."
And if that doesn't do the trick, then the final unanswerable insistence: "Nothing else To Be,-- anywhere!"
