This Day in Nuremberg
The First Amendment grew out of an experience which taught that society cannot trust the conscience of a majority to keep its religious zeal within the limits that a free society can tolerate. I do not think it any more intended to leave the conscience of a minority to fix its limits. Civil government cannot let a group ride rough-shod over others simply because their "consciences" tell them to do so.
