Why do some users have a problem with repeat questions?

I’m not talking about a question that was asked yesterday, or even a week ago. I’m speaking of the questions that were asked months ago or longer, even years.

Why the need to make a statement about the question being asked before, then not provide a link to past questions? I feel these statements derail threads and are not helpful.

Example: “This question is asked every year”. How is this statement helpful? Should we do away with all holiday questions now since they are asked every year? All seasonal questions because they are asked every year? Can’t there be a discussion without someone nitpicking because the question was asked before?
