I think it's important for atheists to think about this. Atheist writers and activists especially. Otherwise, we're just arguing for the sake of arguing, a form of mental exercise done at the expense of annoying people. And the kind of world we decide we're trying to make is going to affect the kind of action we take about it.
In my perfect world, I would like to see religion gradually disappear from the human mindset. "Gradually" meaning over the next, say, one or two hundred years.
So let's move on to the more scaled-back, more pragmatic vision.
(a) religious believers respected other believers and their beliefs — including atheists and our beliefs;
Daniel Dennett talks about this a little bit in his book "Breaking the Spell." He argues that the essential baselessness of religion — the fact that it's unsupported by solid evidence or logic, the fact that it's essentially a shared opinion rather than a body of knowledge — actually makes people cling to it more tightly, defend it more vehemently, get more upset and angry when the ideas are questioned. And it makes people more likely to build elaborate cultural defense mechanisms around it: from the tacit understanding that questioning religion is ill-mannered, to the codification of religious beliefs and practices into harshly- enforced law.
