Are Myths Valuable?

[Alan V]

I remember both The God Delusion and The End of Faith as making a whole series of arguments, not all of which I agreed with.  People are allowed to make arguments even if we don't agree with them.  

Summing them all up as competing mythology is judging them by theistic standards.

Im saying they utilize much of same functions of myths, and not commenting on whether the arguments are true or not.

Those functions are less about the facts being presented but the sort of narrative that houses them, the elements that inspire atheists, to come out the closest, embrace the sort of clarity of their perspective, recognize the deception and delusion of others, motivate them to gather together, establish communities, in opposition to what they perceive as the dark forces of religion, embrace certain sets of heros perceive certain types of villains, the peddling of certain values, etc

So are you saying people will always act by myths, no matter how rational they pretend to be?
