Seems to me we should both take a deep breath. For my part, I cannot see wherein lies the conflict of interest. My failure to answer the question to your satisfaction lies in the fact that I apparently do not understand your point. Returning to the Penn's video, he compares religious morality with that of non-believers. He states that believers behave morally because they fear punishment, whereas non-believers do so simply because it is the right thing to do. Penn is wrong. As a general rule, believers and not-believers, when they behave morally, both follow their intuition of what is right and wrong.
But if you ask a believer why they trust their conscience they will reply that God instills conscience into people to guide them. As seen above, the atheist trusts his/her conscience because it developed by a process of evolution and as such it secures a survival benefit. Or according to Penn, just because. Sure that is a simpler, but its just an unsupported opinion and not a basis for claiming the 'high ground'.
