This actually brings up a point which I'd been hovering around which never made it into the original post. For me the most frustrating aspect of faith is that it is seemingly often used as a substitute for logic. Personally, it's not good enough for someone to say to me "well, I don't understand it, but my deity says so, and I trust my deity". I'm sorry, but that deity needs a reason. If a behaviour can't be justified using rational argument, then it isn't strong enough to be imposed as a universal moral code. If the divine can't make logical sense, then again, I'm in a position where I have no interest in enabling an unreasonable deity. To say "well, it is beyond our limited understanding" is a cop out, because you could say that about anything, and there's then no reason for preferring that particular moral code over any other in the absence of evidence.
