I posted a question to SO, and it was closed as a duplicate, I then posted several comments pointing out that it was NOT a duplicate, that all of the answers to the supposed duplicate were not relevant to my question, and it was reopened. One person answered (with a subjective answer), and the question was closed as not constructive.
Where should you argue that a question was closed incorrectly? Just in the comments? Those quickly get hidden due to the number of comments. The accepted answer to this meta question sorta implies that posting it to meta is the right way, but that seems wrong to me (not sure why, just feels off). Or maybe there's a Meta tag that should be used.
EDIT: Note that while I'd of course like it if the question was reopened, this is intended as a serious question for future reference if and when my questions are closed.
