Meta: One problem with this thread is that it immediately frames all questions as "stupid". I'm not sure questions should be approached from the perspective of "This point must be wrong since the Sequences are right. How is this point wrong?" Some of the questions might be insightful. Can we take "stupid" out of it?
"Uh...stupid question?" is a fairly common way of introducing a question that doesn't seem to have been addressed, but to which everyone else seems to take the answer for granted. It doesn't presuppose the correctness of the material being questioned. It's a diplomatic way of saying "either you've not explained this properly, or I've missed something".
I would rather keep it as "stupid questions" (a known turn of phrase referring to this specific circumstance, which is how it's used), rather than something more awkward yet marginally less ambiguous.
