I think your blog entry is well said. Sometimes we are preaching to more than the choir (pun idiom intended

). The people you address in the blog, those who use the rationale that science is just a different religion, use that rationale to reinforce their own decision to ignore evidence. Explaining the difference between faith which is dogmatic and evidence which accumulates with conclusions which change does little to change some god believers' understanding because the misunderstanding is there willfully. It is there to block the contradiction between the observable evidence and their non-evidence based beliefs.
In order for that faith belief to exist and evidence based beliefs to be discounted as simply another religion, one has to maintain at an unconscious level the fact science and evidence based beliefs are successful and god beliefs are not. When we bring that fact to the conscious level we point out that the core difference isn't underlying belief systems, the core difference isn't underlying premises or basic assumptions. Those are differences, but they are not the core difference. The core difference is evidence based beliefs are successful.
I have been using a similar talking point (remember me and my Karl Rove talking points, Phil?

) when I am discussing evidence based medicine with people who aren't quite convinced their superstitious belief based medicine is wrong and the evidence right. I point out the same thing you have in your discussion of the success of the physical sciences. I point out that the reason we know evidence based medicine is right is it works. It is successful.
I have also been arguing for a while now that allowing the rationale that something called faith based beliefs actually exist and are separate but [fill in your preferred adjective] to evidence based beliefs is a fallacy. Instead there are evidence based beliefs and non-evidence based beliefs. For skeptics (we need a better brand, BTW) to accept faith based beliefs as valid on some other plane than evidence based beliefs is ignoring the fact that we reject all other non-evidence based conclusions but somehow give a pass to certain (but not all) god beliefs.
I understand the reason for the pass. It's not worth dismissing all the skeptics and scientists that haven't let go of their god beliefs, and I don't want to change the direction of your thread. But I do want to point out that I think giving certain faith based beliefs a special place as separate from evidence based beliefs actually supports the idea you are arguing against. It elevates that rationale that faith based and evidence based are just two different belief systems. It lets that inconvenient fact that evidence based beliefs are successful where faith based beliefs are not fade from view. Faith becomes successful in one place and science is successful in another.
But that isn't true. I know many people, skeptics among them, don't agree with my view here. I don't buy exactly that faith in god provides [again fill in your choice]. I think such a conclusion is not evidence based and there is an evidence based way we can look at the same thing. The belief one has faith in a god may provide [whatever]. Belonging to the group may provide [whatever]. That is what the evidence supports. The evidence does not support that a god is actually providing [whatever].
I think we should stop reinforcing the concept there are faith based beliefs and evidence based beliefs as two separate but [your adjective] belief systems. God beliefs may indeed (or do) comfort people. That is the evidence based statement. It's a little harder to maintain god beliefs a skeptic or scientist has not let go of when we don't allow the pass for certain god beliefs by identifying something called faith based beliefs. I realize that and I'm not trying to make a big deal here promoting atheism. I'm just saying it's time to discard the two belief systems. Faith based beliefs are not any different from other non-evidence based beliefs. Just as evidence based beliefs are not just another religion.
