Asking for clarification on a Question is not only permissible but is welcomed. See this question asked by Caleb on Meta 2016. He asks “When should the comment feature be used and when should it be avoided?” When is a comment not a comment?
My question has to do with the use (and perhaps abuse) of posting comments to Answers. This is what Caleb suggested:
>Comments on answers…
may ask for clarification about how a point answers the question if it isn’t clear.
may ask the answer to further explain some aspect of the question not originally addressed.
may correct factual details that can be reasonably corrected by the author without changing the substance of the answer.
may inform the author that they missed something about the scope of a question (or that a question was edited) that they should take into account in their post.
should not provide alternatives to a completely wrong answer. If an answer is just wrong and you feel the need to set the record straight, vote it down and then hit up that answer form and submit a better entry.
should not explain how the beliefs described in an answer are wrong theologically. If they wrongly represent the theological tradition asked about in the scope of the question that’s one thing, but if they are just flat out wrong then stay away from that comment link.
What if a comment is argumentative and the person who posted the answer is disinclined to enter into what looks like a debate on theological differences? Is the person who posted the answer obliged to respond to comments? Or are they at liberty to disengage and leave their answer as it stands?
P.S. I have no idea what tags are applicable here, so please feel free to add some.
