I believe your line of thinking will become more common. I believe all this does matter to you, however. If it didn't, why would you dwell on it like you do?
We're all products. If I dwell on it, it's a reaction to something... Namely, geography and the buckle of the bible belt. If I lived somewhere in which religion wasn't at every corner, I would probably think less about it.
As much as I'm not religious, it still shaped who I am as a person... So, there is that. I'm just reflecting now.
