Recently, it feels to me that every single poster who had a question closed comes ranting to Meta, with accusations of unfairness and high-rep users' power trips, insinuations of a Vast Unicorn Conspiracy and attempts at rule-lawyering (most commonly "many similar exist", but such pearls of absurdity as "I want my question to be closed differently" are also becoming common), possibly with a side order of Godwin. Essentially, though trying to masquerade with Highest Moral Principles (tm), it usually boils down to this one question: "How dare you close my precious unique snowflake of a question 'Foo or Bar which better kthxbai'?!?!one!!??!"
I've tried searching high and low for a similar meta-Meta question, but all I found were myriads of recent questions on this same topic. I'm aware that Meta works as an appeals process in such cases, but it seems that the site is being overrun with such persistent fillibustering and pointless defiance of the rules ("I don't care what the FAQ says, me want, me post!").
Note that this is not limited to new users - recently, I've seen such questions from people who have been on SO for many months and otherwise interact sensibly with the site - but just look weird at one of their questions and they go crazy. (I don't find an account hacking of such scale plausible)
So, essentially, do you see a way out of this? I'm thinking that closing these Meta questions as duplicates of a wider historical explanation "why is this-and-this, noted in the FAQ, done in such way?" might be helpful ("why not subjective?" -"we tried, multiple times, and almost drowned in them as everyone felt compelled to add one (or ten)", laid out in greater detail). These questions possibly exist here on Meta, but I seem unable to find them - could you point them out?
EDIT: I'm NOT suggesting to get rid of this "appeals process", that would be indeed dangerous, as @yms points out. What I'm trying to say is this: iff the closed question is found to have been closed correctly ("gimme codez","what is your favorite X","Foobar sucks", you know the drill), I'm suggesting to close the resulting Meta question on "my question should be allowed on SO" as duplicate of "why is subjective not allowed, how it was tried and failed". However, I'm having trouble finding those wider explanations; am I just failing at search, or are they still waiting to be written?
