Disregarding my personal opinion on whether this question is, or isn't, off-topic.
Here's my two cents on disputing Review Audits on meta.

#Don't bother#

By design reviews take several votes, it takes a consensus of people to close a question.
This also means that people are allowed to disagree, but they have to abide by the majority vote.
The fact that you disagree with a particular closed question, or want to close a question that others don't is just fine.

Your opinion matters, the fact that you want to do reviews and care enough to post on here (in a civil manner) means that your opinion probably matters more than most.
But a review audit is the place where your opinion doesn't actually matter it's trying to trap people who are inattentive while doing the review queue.
It's not trying to test your knowledge of the subject, it's not trying to spark a discussion on the merits of the question.
It's trying to catch out people who just mindlessly spam a button.

You're not one of those, you've in effect been trapped into arguing with an automated system here.
So don't bother, accept that you disagree and think this question should be closed as a dupe.
Perhaps place a close flag on the question yourself, and move on. You've voted.
