I agree with your critique about the community attitude, so I sympathize with your position. However, speaking as a non-Haskell learner with a Haskell writing friend, I don't think it's fair to dismiss the notion entirely.

Haskell is pure functional programming, and it's structure actively discourages a lot of the more common practices in iterative languages. I watched my friend struggle with a very simple web project for weeks while he was learning the language. At the end of it all though, when it finally came together and worked for the first time, he was confident about its behavior in a way I'm not sure I ever could be with the code I write regularly. (I'm a game programmer, so I write a lot of C++ and dabble in Python and Lua.)

I think there's something to be said for the journey that Haskell necessarily takes you on. I don't think the upper skill ceiling for good Haskell developers is any higher than other languages, but the barrier for entry certainly seems to be.
