I haven't read the whole thread,sorry, so this point may have been made, but I think, in line with the thread title, we should be on the same team in a good number of areas, not the leading away from god bit, but the bits we do agree on.
Most of us who are without "religion",some without a god too, whatever label we put on ourselves, most of us agree that the way to live is by the "Golden Rule" and that wherever possible and within our power we should strive to make the World a better place.
I think in those areas of agreement we should be working together, and maybe we should be spending more time and effort on those areas.
A member of a Humanist group, who is also an atheist, as are nearly all in the group, said to me recently "For a group such as ours, we do waste an awful lot of time talking about god".
As a group here it is great to waste time on all sorts of things, its part of what JWN is, but maybe we can work unitedly for "good" quite a lot too.
