Part of allowing the discussion is to identify who is an allied, who is a enemy and who is neutral, and then focus the refuting accordingly. Take climate change. Is those who think we are currently in a run-away scenario friend or foe? It is very easy for people to define them as foe because their views and suggestions are different, and from there put them in the climate change skeptic side even if they share nothing in common with that sides view. Without open and fair scrutiny you get the political situation of "you're either with us, or against us", and from a historical perspective that tend to do more harm than good regardless of what the movement stand for.
