Or maybe you have a different definition of "religious" than I do? But no, it must be that I lack the right cognitive tools. Sheesh.
If you are a member of a religion, the things you have “faith” in are right there in front of your awareness. If you don’t have religion, the metaphysics/mythos/philosophy your reality is based on is often never acknowledged. The “super rational” can be the worst at denying this and best at handwaving away anything that doesn’t fit into their sense of reason.
Maybe I live in some kind of intellectual bubble, but me and the vast majority of my atheist friends are all too aware of the fact that the rationality ends at some point, so I've gotta disagree with this pretty hard. In fact, I'd be hard pressed to find anyone I know personally who thinks it's rational all the way down.
