If it's an officially Christain state, with the establishment clause repealed, then everyone will know what they should believe, and there will be "unity" -- yes, some people believe that -- and everyone will be entirely free to live as tradcons prefer.

It's as if they've missed all the centuries of history that demonstrate the downside of a state-enforced creed.
