Besides the topics themselves (which is clearly controversial in at least this case) I don't think "How would you..." questions can be ever considered acceptable as:
- They are list questions (each person can give a different correct answer). List questions are bad.
- They are never fact-based, they clearly invite speculation by presenting a hypothetical situation.
- They may disguise any off-topic or not appropriate question. E.g. "How would you respond to <insert whatever rant here> as a Christian?"
As such they should be closed as non-constructive.
