Second, if bad yet strong moral beliefs are superior to weak but tolerant amoral ones, then your entire concept of moral absolutism is exposed for the sham and fraud it is. It reduces morality to sheer power over others and the justification to do to them what you think you are entitled to.

Nonsense. The ability of a society with strong convictions to destroy a society with no convictions does not prove their convictions are superior, or even right. It simply proves that an armed evil person is generally going to win over an unarmed good person.

An amoral society is a disaster waiting to happen. There is historical precedent for this. If anything goes, eventually, everything will.

I believe moral codes can be discerned from the facts of reality the same as physical laws. I don't believe that morality can only come from supernatural sources, or by somehow absorbing the general gestalt of a society by osmosis.

If we train our children to be moral sponges, we aren't going to like what they pick up.
