@timur,
I like Leadfoot so I'm not after him, and I almost get his intention, by now, when he started the thread. I take it he meant is for a kind of clarity. But I agree he may not have talked with real life atheists.
US atheists can be quiet in social settings, or at least used to be, avoiding aggravation in daily life.
Americans of my experience (figure California, already an odd place) don't usually burrow into acquaintances deepest thoughts. Well, maybe in the seventies. I still have California friends and am not sure where some of them are now on the religion scope; I just remember these friends as good people.
