Dennis Prager makes good argument against Richard Dawkins
To put this as clearly as possible: If there is no God who says, "Do not murder," murder is not wrong. Many people or societies may agree that it is wrong. But so what? Morality does not derive from the opinion of the masses. If it did, then apartheid was right; murdering Jews in Nazi Germany was right; the history of slavery throughout the world was right; and clitoridectomies and honor killings are right in various Muslims societies.That's an interesting point. Whether or not evil beliefs of Muslim societies and communities are the result of indoctrination, what remains clear is that, if their belief system - religious or otherwise - advocates repulsive ideas like murder and violence, then "opinions of the masses" does not bear validity, because murder, quite simply, is wrong.
Prager may not be without faults, but he certainly can offer some good views when given the chance.
