Sharia law is incompatible with all forms of democracy and republics in which sovereignty is, by definition, vested in the people . Sharia law insists that sovereignty resides exclusively in god and grants itself the universal, unalterable and final authority over everyone on the planet.
Any proposal to introduce Sharia law into secular democracies is a direct attack on the principle of separation of church and state. Opposition to Sharia law, or to any law rooted in the arbitrary tenets of one religion or another, is necessary to support the rights of all to follow their beliefs as their consciences dictate. Freedom of religion is impossible without freedom from religion.
Continued vigilance and active defense of our shared secular traditions, commonly derived from the European enlightenment, and gloriously encapsulated by the framers of the US Constitution is our best and probably only guarantee of freedom of thought, belief, and action.
Repeat after me: Freedom of religion is impossible without freedom from religion.
Personally, I would like to die with a sword in my hand and voyage to Valhalla in a fiery long ship to spend eternity feasting and drinking among the gods. Thanks to the principle of separation of church and state I can do that; no matter that others might doubt the very existence of the mighty Odin.
P.S. Thor just reminded me that Valhalla now supplies non alcoholic beverages, halal and kosher food on request.
