Why does it have to be one way or the other?<quoted text>
Why should an atheist care if they are less or more moral?
But, since you mentioned it, you must think belief in an invisible deity has some moral advantage? Maybe you think that if you didn't believe in a deity you would be some sort of psychotic murderer? If so, please keep your religion. Not all of us need such a crutch.
But, just for fun, please tell us all what moral code you can show originated from your religion? Just 1 moral precept you can actually show humanity would not have without your religion?
