Here's a more nuanced take on the question of fading religious faith, from Adam Gopnik in last week's New Yorker:

Among Gopnik's points: Arguments in favor of naturalism (as opposed to super naturalism) have existed for centuries. One point of interest is how society and culture changes to make these arguments acceptable.
He discusses how physics is more compatable with religion than evolutionary biology.
He talks about how specifically atheistic arguments have been ineffective compared to (his example) Gibbon's discussion of the worldly mechanisms by which Christianity triumphed in Rome.
He says, "...we arrive at what the noes ("no" to God)... really have now, and that is a monopoly on legitimate forms of knowledge about the natural world." Herein lies my disapproval of "The Athiest". His argument is already won. Beating religious folks over the head with it is like the Seattle Seahawks challenging a Pop Warner football team to a game, and then tauntng the 100-pound kids after every bone-jarring tackle.
I'm not sure about Gopnik's conclusion -- which is that life has become so pleasant that we no longer need the opiate of God. However, by reading and commenting on the article, perhaps we can raise the level of this discussion (which wouldn't be difficult).
