Since we are talking about assessments and decisions about a course of action and not values, the question falls apart. I think it was intended to be a trick question calling you out as a hypocrite but from what I have read of your comments on HN your answer would run more like:

A: Examples of a better way to phrase the question.

A: That for some category or type of person the question won't make sense, in which case it's better to ask a different question--or perhaps not to engage in conversation.

You might start by asking for what evidence--experience, observations, or stories--have framed their approach before asking for them to speculate about new evidence that would cause them to change their decision.

I have used your approach and found it effective in dealing with managers: is there any new data or information we could gather that would affect your decision? If the answer is "no" then you know that you are dealing with a political situation (small "p" as in organizational politics) not a problem solving one.
