I think you focus on the wrong problem. It is ok to be wrong and if someone can prove it to you, be happy to have learn something new and thanks him/her. Of course, to do that, you need to have an open mind and always act on the safe side. Instead of saying: "You stupid idiot, haskell is not purely functional because there are monads", you're better with "I'm pretty sure haskell..." or "I think Haskell..". This way, you encourage people that might know more than you in that subject to speak and help you instead of aggressively attacking them. There's nothing wrong in being wrong. And to be honest, I think it's the only way to learn :o
