One of three things happens with questions like these. One option is it turns into a hunt to find a particular blog post, paper, or book where the person clarifies their stance. Resource requests like this have been determined to be off-topic here. Another option is that the answer hasn't been given anywhere and people guess or share their opinions. A third, but extremely rare option, is that the one person (or in some cases, one of a small group of people) shows up here to answer the question. We expect that questions are answerable by the broader community and not require a specific individual.
I'm not sure that I would have chosen "opinion-based" as the reason for closure. I probably would have gone for the resource request reason. Both are valid, though, since this is likely to become one of the types of questions that we've decided don't belong here.
