I don't think that's really true in the Haskell community. I've seen lots of self-criticism of Haskell on /r/haskell. Even SPJ himself is willing to admit that Haskell has design mistakes. Some things Haskellers readily admit as issues with Haskell: - the String type - records - laziness (more contentious, but many people agree that this might not have been the right choice) - error messages - the prelude Essentially, my experience has been that Haskellers are willing to accept that Haskell is not perfect.
