Only the religious element of the three major components.
Goes without saying that there would be NO sharia Law, unqualified adherence to civil final authority in all things, and ZERO tolerance demanded of muslins in America for the armed militant component of their damned "religion".
But as I said, that is no longer the islam we know and love and, I'm convinced, not likely ever to happen.
I would suggest that even the purely theological aspect would be antithetical to America as we are sovereign citizens, whereas Muslims are “willing slaves of Allah”.
