There is a different and better way to put this: most people are completely unaware of the foundation of irrational nonsense that their worldview is based on. (yes, even, or especially so if they base their worldview on rationality)

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.

can you elaborate on this? This is the kind of philosophical analysis that I think most secular thinkers lack. I know there are rigorous atheists who are capable of understanding their ideology, but they are few

So? Most religious people are incapable of understanding their own religion, too.
