Irrationality of theism?
I guess I have yet to see a convincing argument that theism is intrinsically irrational. I completely agree that in practice, theists are often far from rational, but the logic is flawed in extending that to all theists. I'm sure I could find irrational atheists. That certainly doesn't make all atheists irrational. The best analogy I can come up with involves Euclidian geometry. The entire body of theorems in Euclidian geometry are derived from a select few axioms. One of those axioms is that parallel lines never converge nor diverge. Euclidian geometry is considered 'flat' for this reason. But there is nothing to prevent changing this axiom and doing so results in hyperbolic or sphereical geometries. The key in this is that these core axioms are assumed, not proven. And by changing these assumped axioms the nature of the geometry is changed.
Starting from this analogy it seems reasonable to me that each of us must form some explanation of reality. At the heart of that explanation are core axioms with which we build a framework to explain the world around us. One of these axioms deals with the existance or non-existence of "god". As far as I know, there is no rational proof for or against the existence of "god", so one must choose one or the other and build an explanation of reality based on this assumed "fact".
In this light, thesim and atheism are in equal footing. Neither is rational. They are both core axioms in a framework of ideas that attempts to explain reality.
So what is wrong with this argument?
