I just asked What can I do if I have a feature idea that was already requested, but the author removed the suggestion in the meantime? here a few hours ago. That is a discussion regarding how to handle when you want to request a feature but you're aware that a prior deleted question requesting the same feature exists. In that question, I quote from this answer from a moderator, which states that it's not a good idea to repost such feature requests, and provide arguments against their opinion.
However, despite my linking to and quoting from the other question's answer, the same moderator closed my question as a duplicate of the prior question. In a comment, they stated that if I disagreed with their answer, I should have posted another answer to the same question. That would be true, if I were merely expressing an opinion, but that wasn't the purpose of the question.
I don't believe that this duplicate closure was correct, because:
- The purpose of the post wasn't merely to express the opinion, but also to ask if my thoughts were correct. I think it's fair to quote from an already existing answer and raise a fresh discussion about it, so one can ask if their arguments are correct or if there are alternate solutions to the problem. This is especially true if potential responses would be larger than what comments can contain, and would better be written out as full answers themselves.
- On main sites, it's perfectly fine to ask the same question as an earlier one as long as one quotes from its answer(s) and explains why they didn't work for them. I think the same applies for meta discussions: if one disagrees with an opinion presented in an answer or comment, and that question isn't fully related to its original parent question (see next bullet), it's completely fair to post a new discussion specifically about it.
- The prior question was mainly referring to main sites and reposting better quality versions of deleted questions of bad quality, so an answer that completely refers to meta sites wouldn't really be answering that question (i.e. my counter-answer against the moderator's opinion wouldn't be a proper answer to the author's question). In fact, the part of the answer which my question quotes is (explicitly noted as) a side point they added in response to comments on that question.
- By the strictest interpretation possible, the final question in my post doesn't specifically refer to reposting; it simply asks for solutions to the problem (of wanting to support a feature request that was deleted). Reposting is mentioned as a potential solution in the discussion but isn't part of the final question, whereas it is part of the final question in the older post.
Is the duplicate closure correct here? Should it be reopened, or should it remain closed?
