I don't know if they'd make it a crime...but certainly both Christians and Muslims would have no problem making gay marriage a crime. Or abortion.Really? Does that mean you are okay with sharia law being established in government institutions?
Wouldn't that be religion dictating policy to the government? I do see a difference
What your saying is like the Catholic religion could make it a crime if a person used contaception
What is the difference when you get right down to it? No religion should be allowed to make laws based on their morality.
I agree fully with you, hence Separation of Church and State...in that regards.
But to put a Nativity scene in a public square, or saying "in God we trust...." is not separation of Church and State. IMHO
