If a posted question is not a question, or it is completely unclear what is being asked, it is best to use the "Unclear what you are asking" flag / close reason. And you should probably leave a comment on the post as well indicating that it's not clear what's being asked (if you haven't already done so).
This is the best suited flag/close reason for cases where a clear question is not being asked. ("Too Opinionated" usually implies that individuals won't get any fact-driven answers, not that the question is unclear or nonexistent.)
