Doesn't it seem to be true by definition, that if there is no state religion, then religion and the state are separate?

If "the state" were comprised of soulless robots, yes. However, people make up our government. People whose morals and ideas of wright and wrong more often than not stem from religion.
My question is the opposite of yours. If our government is of, by and for the people, how can religion be totally left out of government and that government still be truly representative of the people? I don't see how it can.
