Q:

How is my meta question from a year ago a duplicate of something asked two days ago?

So maybe I just don't understand how duplicates work. I had a meta question which I asked a year ago. It was recently marked as a duplicate of this question, which was asked 2 days ago.
I'm not totally convinced that they are actually duplicates, especially since the new questions uses the support implied from votes on my question as part of its premise (which seems like some weird circular logic if my question is a dupe), but more importantly, how can a question be a duplicate of something that didn't even exist at the time of asking?

A:

For meta questions, the same reasoning holds as for questions on the main site:

If the new question is a better question or has better answers, then vote to close the old one as a duplicate of the new one.

FWIW, I agree that the banner text explaining the closure

This question has been asked before

(emphasis mine) is misleading.
