That's actually a good debate. I disagree though. I'm sure there are plenty of atheists out there who believe in the individual over the state, the RKBA for it's original intent, equality of man, etc. Not to say these principles don't have Biblical origin, they do, but I believe one can believe in them without explicitly believing in a deity.
Without God we are nothing more than animals (like Darwinists teach) and the only law is the law of the jungle, "the survival of the fittest."
Without God, there can be no objective standard of morality, only competing man-made immoralities mixed up in a relativist morass.
