Does the American Constitution allow freedom of religion?
Th passage you cited guarantees freedom of religion and simultaneously the freedom to have no religion if that is your choice. (However, please note that teh U.S. Supreme Court has twice ruled that for all legal purposes, at least, atheism is a religion. And it is a system of belief about God — that there isn’t one.) Christianity, other religions, agnosticism, and atheism are all protected under the First Amendment, and that is the way it should be. It’s interesting that every atheist I’ve ever encountered can give you a detailed description of the God in which he or she doesn’t believe. Present any other idea about God and it’s the atheist as much as the fundamentalist who will insist that your idea of God cannot be God, that definitionally, God must be defined his/her way (as that God in whcih he/she doesn’t believe.) Taht’s as much blind faith as any religious person has ever exhibited.
