Ok, I looked, but haven't seen a thread here yet about off-topic specifically in the comments, more specifically where discussion begins as on-topic, and then moves to off-topic discussion. I'd like to start by clarifying that the question itself was not disputed as off-topic, and I think roughly fits into the on-topic guidelines for pertaining to clinical guidelines, pharmacology and public health(perhaps). The question received a brief answer via comments, and a discussion ensued. Pretty quickly the beginnings of an answer emerged, but then the conversation veered off-topic. That is when moderators moved the whole of comments to a chat. I personally don't like chat, as StackExchange is a Q&A platform, and I think it creates a lot of extra reading material, that might distract from getting to the answer. Also there is some fuzziness about persistence / permanence of chat transcripts.
I am wondering why the whole of comments had to be moved to chat, rather than just deleting the offending / off-topic comments(preserving on-topic comments), and perhaps opening a chat for optional continued discussion.
I have looked at Code of Conduct and Expected Behavior, and I don't think I have violated any rules other than my gradually devolving into my personal medical story in the comments, although in my defense, my off-topic comments were initially received without any corrective action taken by moderators.
I see a lot of unanswered questions around StackExchange, and justifiably, not all questions have an easy answer. I think comments can help guide the conversation, and lead to better answers. Therefore I am wondering if it is possible for the comments from the beginning of the discussion, where it was still on-topic to be restored to their original place under my question, and for the chat full of off-topic comments to be deleted. I don't see how it benefits to have good information hidden in a chat along with a whole bunch of garbage.
I have said this in meta.stackexchange, but perhaps I should say it again here. I'd like to sincerely say sorry to Carey, for making such a big deal out of all of this! It is now clear that I missed something while writing in the comments, and perhaps that lead to a misunderstanding. I'd also like to reassure the mods that I don't intend to contribute to any more off-topic discussion, and it will only be the best behavior from here on out.
