Because it strikes me as a fundamental question and I'm exposed to it constantly?

Now this is something different from the impression the post left me with. It is one thing to have emotional response to something, and another thing to have a judgment about that emotional response. From your post, I understood that you have emotional attachment to religious beliefs, but you don't approve of that attachment, it's not part of yourself, you don't actually think those beliefs are true, and so you asked about strategies for cutting that unwelcome not-part-of-yourself off. But for the question itself to be deemed "fundamental", you need to believe it has any merit, in this case hold religious beliefs as not obviously false.

(Whatever the case, stating your situation more clearly would be a first step.)
