Okay, let me share the way I see it.
They are not duplicates. They are related questions. They share 1) content of answers (the quotes) and 2) topic. But they 1) have different phrasing, 2) ask about different things, 3) have different actual problems behind them. I can't believe there are people who seriously call them duplicates. Did you read the edited versions? Some of the information is duplicated, but not the questions themselves. It reminds me of Orwell and doublethinking.
I can understand if you say you're trying to make yourself less work to do. Questions like mine doesn't worth it and so on. I can understand if you say that questions must have actual problems behind them. You're putting much more effort into it and have much more experience with it. So you should know better if it makes sense or not. But let us finally call things by their proper names. Otherwise make yourself clear in HelpHelp CenterCenter. When did you last read these articles? One of them contain link to Dr. Strangedupe: Or, How I Learned to Stop Worrying And Love Duplication. And they're talking there about questions which even I consider duplicates.
There is a value in having these questions. Presenting users with answers for the questions they're searching for is a good thing. They: 1) don't need to inspect related questions, 2) won't create a "duplicate" because they didn't find the question, they were searching for. Again, already mentioned article suggest even more liberal approach than mine.
