For the record, I DO NOT believe there should be a State Religion
and I believe most people do, as well.
Why is it "bad" or why do you think it is bad ?
But as Locke argued and as I believe,
the government lacked authority in the area of individual conscience.
and the social contract should avoid it....
The story of Henry the Eighth and his daughters should be enough warning for us. With the common man caught in the crossfire, the English crown switched religions back and forth and then put to death the "heretics" that followed the father or the rival sibling, using the "faith" as an excuse. A difference in dogma became a treasonous act.
If the State chooses a religion, than any deviation from the religion ends with burning people at the stake or hangings.
Imagine if Romney were elected and then proclaimed that Mormonism was the official state religion. That EVERYONE must convert or be tried for treason.
Or it turned out Obama really was a secret Muslim and proclaimed America an Islamic state outlawing all other faiths and then arresting, jailing and putting to death anyone who refused to convert?
That is what a State religion becomes.
We enjoy a freedom here that must NEVER be compromised. We are free to worship ( or not ) as we please without the fear of punishment from an opressive monarch or regime.
We should protect that with our lives.
