@mevaqesh often an exact duplicate is a sign that one or both of the answers needs more tuning to specifically address its question. But here the question was closed as a duplicate, so maybe that's not relevant.

Having the same exact answer on a question and its dupe-target feels a little iffy to me; it's not a rules violation AFAIK, but you can see how someone might find this one, vote on it, go to the dupe (then or later), vote on that... were it my answer I would delete the one on the closed question.

So I thought it was an oversight and thus asked about it.

@MonicaCellio Not necessarily. For example two questions may not realise that they are merely specific examples of the same general principle that answers both perfectly. This happens not infrequently.

@MonicaCellio This is especially often true given the nature of the site being intended for theoretical discussions; not specific individual issues. But I digress. I deleted the post as per your suggestion.

@mevaqesh true, we do see that here. If I find myself answering A and B, which are both special cases of C, then I try to add to my C-based answer something that specifically addresses A (on the one) and B (on the other). Something like "For example, this principle applies to A by..." -- that kind of thing.

That way the OPs get their specific answers while also learning the broader topic. I haven't read both questions and the answer here carefully to know whether that approach makes sense here.

Why are there 19 posts in the close vote review queue? ...guess I'll find out...

...looks to me like someone was going through history and mass voting to close. (Whether justified or not we'll find out, I suppose)

...the review queue serves the purpose of finding out what some users believe about whether certain posts are on-topic, but if you're going to close vote a lot of posts that have been open for a long time from one tag or type of question, you should consider posting something about it on meta first, to see if community consensus has changed / considers these posts on topic

Just saying

And also read a little more closely before close voting. judaism.stackexchange.com/q/14844/5323, for example, is entirely on topic AFAICT because it's about jewish-books.

@Shokhet the identified reasons for closure were too broad or unclear. Nobody said it was of topic, afaik
