Who/what are the two witnesses in Revelation 11? asks for text-supported interpretation of an image in Revelation. The question has 7 upvotes and 4 favorites, which by this site's norms is significant. However, it has attracted (at this writing) four sub-zero-scored opinion-based answers where people make assertions about the imagery without supporting those interpretations in any way.1 It also has upvoted answers (including one at +9 and with a bounty), so it seems the question is answerable.
Our broadly-accepted policy says that these answers should be deleted (or edited, but the authors haven't done so and comments were left):
If a post is essentially an opinion-based argument or testimony, it doesn't fit and will need to be removed or edited.
It's clear that these answers need to be deleted. My question is about the question. Is there some wording change that would help deter these kinds of answers, or is Revelation just prone to this sort of thing (it being full of imagery) and we're likely to have this problem more on that tag than others?
I'm mainly asking what we should do about this question, but if there are things we should do differently for future questions too, either all of them or ones of specific types, please share.
