I wonder if it is theism which is the stumbling block? Or the unwillingness of those involved to give up on a lifetime of ideas, which in many cases, I think due to overwhelming support, is working.
Yes there are those believers for whom belief is strong. However I think the majority are simply adhering to a lifestyle learned from childhood out of fear. Not fear from scripture but fear from family and friends looking down on them. Most I have tried to talk with, are unwilling to even have a discussion, knowing all the arguments themselves, agreeing with them, but it seems a willful ignorance keeps the family happy. At least in my experience.
If those people would let go, the sheer numbers I think would show we are not the few, but the many. Effectively taking the missiles out of reach of children.( an obvious overstatement, but without numbers, at least those who want to wage war, need an actual plausible reason to do so, instead of whose book is right.)
To do so we must remain neutral, as this is our primary stance here anyway. Present ourselves continually the voice of reason. But we must be heard. It was reading Dawkins I decided I needed to speak up(yrs later still trying to), and, discovering several wrong ways to do this, started seeking advice/opinions from others.
The bigotry faced by atheist is atrocious, if this can be faced and overcome, I believe unbelievers will come out of the proverbial closet in droves.
It's the old stigma of a crowd of kids watching a bully on the playground pick on a nerd. When someone in the crowd finally stops and says the bully is wrong, the first to do so is usually frowned at, none speak up so they can fit in with the crowd. So the bully still gets his way.
The Bully = religion
The Crowd = well, the crowd(masses)
Nerd getting beat up = atheist
