What should we do about questions that subtly seek application beyond the text itself by asking about the meaning of something that has a plain meaning?
I think the distinction between a textual questions vs. a theological question is subtle in these cases, and I agree that the OP's intent plays a role. At the same time, the text in this instance is very clear. The real underlying question involves the application of this text, which is off topic (i.e. "Does it really mean what it says?"). This is evidenced by the fact that most of these questions merely attract answers that proof-text a theological concept from other Biblical texts to make a case about the text being inquired about - which is theological rather than working from the given text and explaining its 'apparent' meaning in context - without elaborating on the implications of the text for modern readers.
Luckily this is somewhat rare and most of these questions are good and can often be clarified with only slight edits (if needed at all). But this particular one and similar ones pop up on occasion and I've always been hesitant to act because the distinction is so subtle.
