Nothing wrong with "spiritual feelings". Atheists have them too. Clearly a mostly secular society is possible even with our biology/instincts, just look at Sweden or Denmark. No need to erase love, sorrow, pity, jokes or art to largely erase religious conflict. It's culture, and we can evolve culturally beyond our current primitivism. I'm with neals; I used to think we'd leave religion behind. Maybe some day "believers" will be a small minority. I hope so. I'm sad to say most of us will not see that day.
