The policy regarding closing something as a duplicate of a broader post has already been discussed.
Recently Jewish conversion? got a close vote as a duplicate of Is it possible for a Gentile to convert to Judaism?, and it got me thinking: the latter question is a perfectly fine question, except that it’s too broad and should be broken into several different questions. If so, it doesn’t seem right that the former should be closed as a duplicate of the latter. (Yes, I know it was closed as unclear, not duplicate. I’m just using it as an example.)
Is this indeed the policy, that posts can be closed as duplicates of broader ones if the broader post is too broad? Or does the policy not apply in this situation?
