Just because you paint a form of destert tribal government as a "religion" does not mean it has absolute protection any more than yelling fire in a croweded theater.
Islam has a simple ultimate goal. Covert to Islam, Submit to Islam, or die. There is no room for a USA government of any kind in there.
ANY islamist would gladly burn the original constitution and bill of rights.
Islam is a government form just as communism was a government form. You just have the useful idiots dancing the PC hoola because they are too naive to realize the real danger faced by this resurgent blood evil.
