I'm going to have to say that I strongly disagree with you. Now, while this country does have separation of Church and State, it is not nearly as recognized as it should be. So, yes this country has and does work on misguided fairy tales(Prop 8, Stem Cells). I don't believe that it is right, it is just the way some things have come to be. And it seems that until people can recognize when to separate their own personal beliefs and its effects others, then things won't be changing very soon. A large number of the United States population is unfortunately hypocritical.
Many are very quick to shout out that the founding fathers where religious, while they also seem to conveniently forget the separation of Church and State.
