Fair enough, let me clarify. My point is that religious believe isn't necessarily more or less irrational than being areligious. Yet professing any kind of faith in God, or anything else metaphysical, is often looked down upon as being more irrational than philosophical naturalism. Sol is doing a great job of making this point.
You didn't need to turn this into a personal attack.
Philosophical naturalism, as you've defined it, is NOT the same thing as faith in the flying spaghetti monster. You're still stuck equating "things that exist" with "things that do not exist" and claiming they are both equally valid.
I have no problem with believing in supernatural things that are not part of the physical universe. If you think ghosts are real, you're not being inconsistent unless you also believe that ghosts can interact with the real world in some way. An entirely separate universe, independent of ours and without any interaction, is not provable but also not theoretically inconsistent. Unfortunately, people who believe in the supernatural seem to derive 100% of their belief from violating that separation. Ghosts are real because I saw one. Magic crystals are real because they healed me. God is real because he answered my prayers. These are each claims that the supernatural is natural, that it has some physical reality.
Belief in something unprovable, but not impossible, is a useless waste of time. What possible bearing could it ever have on us, if it cannot interact with the real world in any way? It can't be explanatory, or predictive, or contextual, or useful.
And while we're on the topic, I should point out that lots of other things that don't exist in the physical universe are still "real" because they exist inside the mind, and thus impact our behavior. "Patriotism" is my favorite example, because we all recognize it as a primary driver of human history, and yet it only exists within human culture. It's an idea, not a real physical thing, but it's a powerful and consequential idea full of beauty and also the potential seeds of conflict. I put "God(s)" and "patriotism" together in the same category. They exist now as cultural artifacts but will cease to exist when the last human consciousness dies out, while the physical universe continues on for billions more years without noticing the loss.
