My opinion is that the couple examples we have seen of this are not good-subjective questions.
I would disagree that they can never be fact-based, but chances are if they do hold potential they could be re-worded better. For example it's possible some "how would you respond to" questions could be re-worded "what is [the protestant] response to" or some other variant where an official or defended position could be expected. If a question could not fit that format, it's likely not a good candidate for good-subjective.
I closed the original version of this question, I was a little bit surprised to see it pop back up here. The second OP definitely fixed the quality problem with the offensive wording, but I still don't think it's a good fit for SE. As you note it's basically a list question where everybody is going to have a different approach.
