Tibet, before the Chinese invasion, was a theocracy, as were the Papal States before 1848, as is Iran and as was Taleban run Afganistan. Not a great model for a constitution.

The US does not allow a state religion. It was founded on religious tolerance, at least between Christian religions.

The UK has a state religion but is far from a theocracy.

Just to recap, you implied the US was a theocracy. It isn't. Your not going to expand on your comment regarding the US and democracy then?
