For this question, I'd like to provide a link to the meta discussion about "is X on topic", so that the (reasonably new) user gets introduced to meta and gets and understanding of why these questions are off-topic and can provide an opinion (answer/vote) if so desired.
The problem is that we have a meta question specifically about this: Should questions about “Is X science fiction” be off-topic?, but the highest voted answer (by far) says that these questions should be on-topic.
The reason that these made it into the FAQ's off-topic list was this answer to another very redundant question that became popular.
ISTM that it's confusing to have contradictory information like this, especially since the question specifically about this topic has the 'incorrect' answer voted highest. We get rid of closed questions so that users don't think "this other question like this is ok", but if they actually go to the effort of looking on meta, they'll find the wrong information.
What can we do about this? There's no "out of date" close vote reason. Vote to close the original (clear, simple, direct, i.e. better) question as a duplicate of the other? Chase down the 10 people that down-voted this type of question to go vote on the original? Vote to close as "too localised"? Flag it for a moderator to deal with it? (What would the mod do?) Put an ugly edit in the question that indicates that it's out of date?
