I think this was well-put. I, personally, detest fictional villains, but that doesn't mean I think they're lurking out there somewhere. And while I might seek to emulate fictional heroes in some respects, that doesn't mean I think I'm going to fly around on a broomstick to catch a Snitch, have a telepathic horse-Companion, or be a dragonrider of Pern.
But thinking about that led me to a realization, of sorts. You see, my own experience growing up as a Christian was probably much different than many of yours, or most Christians out there. I never bought into the whole thing the way most people do or did. I never considered that the Bible was intended to be taken literally. I read the Bible on my own (usually because it was less boring than listening to a minister give a sermon) and I thought of it like I thought of the fiction books that I practically devoured on my own - something that you can learn something from, but not the Literal Truth and Word of God. Part of that is because I mostly focused on Genesis, Exodus, and the New Testament, which are based around mythic doings.
So while I might have absorbed a good bit of the morality of Christianity, I never really accepted the doctrine in the literal sense that apparently is expected of Christians. I tended to look for explanations that made sense, rather than handwaves that treated them as miracles, and my parents (especially my mother) tended towards that approach as well. For example, the feeding of thousands with only a few fishes and loaves makes much more sense as inspiring people to share what they actually had with each other so nobody went hungry rather than magic multiplication, even though magic multiplication is what most Christians believe in. The only difference now is that I don't think I'm likely to be able to figure out rational explanations that will be accepted by Christians in general; most of them are far too beholden to the 'magic' explanation (and the belief that the 'magic' still exists out there, even if they themselves never see it).
