Islam is antithetical to the U.S. Constitution. Islamic law is in direct conflict with the 1st, 2nd, 4th, 8th, 13th & 14th amendments.
In Islam there is no such concept as individual liberty, right to government by consent of the governed, or equality before the rule of man-made law under Islam.
Islamic law (shariah) directly contradicts the established legal system in the United States.
