Christianity is already in the crosshairs of fedgov types who would love to kill it.
If we openly give them the power to restrict one system of belief, even one as repugnant and vile as mohammedanism, they will take that inch and run a marathon with it. No religion will be safe from the sweeping gaze and power of the federal government once they get the lumbering beast into motion.
So NO, fight the mohammedans with ferocity and fire if needs be, but do it on the field of battle, not in the arcane and morally bankrupt field of government fiat because we will all suffer.
Once the iron fist starts swinging, it is indiscriminating and relentless.
It is called slippery slope...
