Shari’ah law is in so very many important ways, simply not compatible with the body of law and philosophical underpinnings of that law, that apply in the United States and most civilized countries across the globe, that there is no known way to even attempt to integrate the other codes of law to Shari’ah law. Too many contradictions appear immediately, and only by abrogating huge parts of the existing law in the Western countries, could Shari’ah law even be applied.
As Americans, there is every encouragement to exercise your religion as a matter of conscience. But there is not unlimited or even implied permission, to use the tenets of your religion to impose your views upon others. Islam is not a religion as the rest of the world sees it, it is an ideology, much like the Bushido code of the Samauri warriors of Japan, or the Justinian Code of Rome.
But neither of these codes, or in fact almost none of the various law systems drawn up by men are in fact tied to a specific religion, as Shari’ah law is tied to Islam.
If the great Islamic thinkers may somehow disentangle the Shari’ah law from the practice of the Muslim religion, then there is some possibility of working a way for Islam to coexist with the great and shining ideals that are the essence of that nation known as “the United States of America”. But until then, Islam remains an ideology, not a true religion, and as such, it may be sharply circumscribed in its application in this country.
"Individual Moslems may show splendid qualities. Thousands become the
brave and loyal soldiers of the Queen: all know how to die. But the influence
of the religion paralyses the social development of those who follow it.
No stronger retrograde force exists in the world. Far from being moribund,
Mohammedanism is a militant and proselytising faith. It has already spread
throughout Central Africa, raising fearless warriors at every step; and were
it not that Christianity is sheltered in the strong arms of science - the science
against which it had vainly struggled - the civilisation of modern Europe might
fall, as fell the civilisation of ancient Rome."
