I've been talking to religionists on other forums for quite some time now and also I was one once; I have also been talking to people of different political bents, and made a few observations:
I don't think the religionists (which is very similar to the conservative/Republican mindset) are purposefully being evasive. Nor do I think they misrepresent or deceive, here I mean the religionists only, but both still have similar relevant characteristics.
Our minds work in lineal ways where space time and causation are important factors to imagination and therefore understanding. It isn't possible to understand what you can't imagine except as math equations or absurd physics formulas. The mind needs to (must) keep things separate in time, place and seeks causation. We are also pattern seeking creatures. This is how our minds collect and sort information to create a model of reality we can deal with. Oddly our language isn't so limited and we can pluck out abstractions from our thoughts and string them together out of order to create very abstract concepts; they are better suited to language than a reality we can call functional. Our minds do not create a very convincing reality in the face of evidence but they do create uniform reality most people can comprehend. By this I mean we see things in a narrow range of colour, tend to orient objects and the world around us in a very egocentric way, we hear limited sounds, we have poor smell etc.. all these are often combined in other species which creates a very different world for them from our human world. For example a bat combines sound and sight in its brain for a single interpretation - it literally sees sound, likewise a bird can see magnetic fields (how different would our science be if we could see these fields?) - try showing load stones to a bird its fun.
So it has been my observation that the frame work of perception differs between the religionists and the non-religionists but both use similar abstractions. I think this is important to understanding. I have read Dawkins, Dennett and Hitchens (others too) where they tend to assume a superior stance against the religionists and even go so far as to call themselves "brights," because they assume theirs is an intellectually superior vision - they assume they are more intelligent. I think this premise is false. I have met remarkably intelligent religionists that if anyone were to call them unintelligent or even less intelligent would only pass a not so very nice verdict on the observer. They simply are not stupid but they do see things differently, that is, they have different abstractions. Now abstract thought is very much like the bat who sees sound and light as similar things; the bat could say we are stupid because we need a flashlight. We could say the bat doesn't see reality because it is different than our own.
So what I am saying is that to the religionists who places their own experiences and "belief" above evidence are doing so because they perceive a causation of their experience that a non-religionists doesn't. This is also why we end up with sky gods because such a model makes sense to a human brain in terms of place, causation and time. So we end up with a god that we can conceive but is wholly unrealistic in terms of something that really could "create" a universe, but we do get something that is easy to imagine. That being said, the scientist does the same thing with very similar effects. Though they would claim their ideas are grounded in evidence a realistic look at science will reveal that this isn't the case. They very much rely on the "minds of giants" from which to leap off of and make their conclusions (faith in the scientific method). As a result science has become every bit the dogmatic (using the work of previous "great" scientists without question) pseudo science (not actually concerned with reality as much as method) full of mistakes (cooking experiments to get results desired) and superstition (trust in laws that predict not explain) that we would expect given the nature of our minds. I have brought up these observations to scientists and other "skeptics" and received very hostile responses exactly the same as I do when I bring up problems with the religionists world view. They deny what is pure evidence because I have hit a limitation of their abstract thought and challenged their dogma, but also, and more importantly, I have challenged what they hold as evidence. I would recommend a book: The Trouble With Physics by Lee Smolin because I have no interest in arguing this point. If this contention raises the hackles of any reader of this post I would suggest that now they know how a religionists feels when their own "evidence" is challenged.
As a religionist I observed the hand of god in everything. My observations were drawn from my personal experience and the experience of others. I drew out abstractions and assembled a world that made sense based on these observations. Now that I am not a religionist I do the same thing only I use different evidence. In fact I have married the two together to some extent. I am lucky that I could escape the prison of religiosity (odds: 1 in 12) but I didn't feel it would do to replace it with another dogma.
So what separates the religionist and the skeptic is only the dogma, observations and what they hold faith in. Both are equally absurd but not in the context of how our minds operate. What I have come to question is which group is capable of the most abstract thought. Physics and indeed any science requires a lot of abstraction but so too does the belief in a god bound by time, place and causation. I honestly believe there isn't much difference.
I tested this hypothesis out on the editor of Skeptic magazine. I sent them an email explaining that I suspected they weren't all that skeptical because they seemed to hold too strongly to a belief in evolution. I received a hostile email back of the sort I would expect had I sent a similar email to a clergyman questioning his belief in god.
So my conclusion has been that the difference between a skeptic and religionist is in what evidence they consider, the abstract concepts they conclude, and the arguments between the two groups is really just an argument of semantics, dogma and belief. There really is no empirical evidence that either side is right or wrong in terms of whether there is a God or not. It just boils down to the kinds of abstractions people conclude for themselves.
Sorry for the long post.
Nice long read Scott. I agree with your conclusion about skeptic. The god discussion will rage on for a while yet I guess. I think it's very important to the future of mankind that religion be leashed, god can take care of itself. I think somewhat like you do about science, I don't think the physical science can fully address the spiritual man and I know organized religion is a curse.
