Even though I couldn't rule out the possibility that I might have some paradigm-exploding insight while, for instance, gardening or collecting stamps, I wouldn't ever say that my pursuit of knowledge or truth is incomplete if I don't garden and collect stamps.
Why should I regard religion differently from other hobbies?
But I could spend a lifetime pursuing truth and only scratch the surface of "everything" without ever giving religion a second thought.
I would say this is because you seem to assume that truth has to do "everything", or that is should answer only those things in which you are personally interested.
While this is not false it's not complete either.
Truth in addition to universally answering many questions also reveals what is not obvious, it also unravels new questions and reveals things like new knowledge and wisdom.
Why considering religion?
Religion isn't only about God or morality or how one should behave according to some set of rules.
ie. I learned from religion something that was far from obvious, something very esoteric and worthy of respect.
I think an individual must reveal this on it's own in order to respect it, esoteric knowledge must be earned.
There is one passage in the bible which say it's not easy:
Matthew 7:14
