How silly.
I suppose you actually think that Govt officials using their position to promote their personal religion in public Govt buildings...is fine UNLESS they pass a law requiring ALL people in the state to sign up for it.
With all due respect this is juvenile.
And, yes. A LAW must be passed for a religion to be ESTABLISHED.
It isn't established IF people aren't REQUIRED to join it.
If George Bush talks about his Methodism, or Billy Clinton talks about the Baptists, or GHBush speaks of Anglicanism, then I could care less AS LONG AS they don't force me to sign up.
It's America. There's lots of differences out there in the culture. Adults recognize that and don't let it get to them.
The genius of the 1st Amendment is that it said, "Just let everyone be themselves; keep your hand off their religion." That way they didn't have little religious gestapos running around the country tattling and getting in a snit everytime someone said the word "God."
