Mass murders, serial killers, professional criminals, rapist, and pedophiles could all say they are Moral people. Who can debate this. They are each right to pursue their desires and beliefs. By what standard do you dare tell the man who is going to kill you for the contents of you wallet, that he is not Moral. You have no right to tell the man who is raping your sister, wife, or mother that he has not the right, or that he is not moral.
What gauge, unit of measurement, or rules do you possible apply to tell them otherwise?
The codes of conduct established by religions. Those standards even if Atheist take over the world and religions are outlawed, they will still have to apply the same rules to keep others in line so they will not take what is theirs. You can call them the "New Laws of Bob", but they will still only be cheap copies of religion's laws. The die is already cast, and the bar has been raised, and all you can do is follow.
