Theologically, no. Because his allegiance is to Allah, the moon god of Arabia. Scripturally, no. Because his allegiance is to the five pillars of Islam and the Quran (Koran).
My allegiance is to Christ first and foremost. If my nation does something that my Christian faith is in opposition with, should I still be required to hold an allegiance to the government and support what my nation does? The Bible has told us there will come a time the world hates Christians. This doesn't mean just outside of the borders of this nation of states, it means everywhere. When that time comes (and it's quickly on its way) where should my allegiance lie then?
I hear ya, but the original question was about "loyalty and "patriotism."
The Founders have already spoken on the matter, and American Christians by and large have followed suit.
