I argue much the same in numerous articles. I agree it's possible to reject religion and to be self-conscious about where meaning comes from. That's the essence of postmodern irony.
But the fact that that sophisticated, enlightened stance is possible doesn't mean its commonplace even in atheistic circles. That's what my article on godlessness is about: the difference between strident, hyperrational atheism which holds up reason as an idol and which isn't humble or cynical enough, but which goes on to make other idols out of money, pleasure, art, and so on, and a more pessimistic, post-Nietzschean or Lovecraftian (cosmicist) atheism that doesn't sugarcoat the implications of "God's death."
