Yes, and in addition to that, directing the discussion to niceness (or lack of it) means you're trying to turn the discussion from
what is being said to
how it's being said. In which case you're not actually even considering other people's arguments or replying to them, but instead talking about how the other people are talking. Of course it matters how things are being said, but in my opinion things are kept quite civil on these forums (which are very tightly moderated).
I don't think anyone here is defending or advocating that kind of behaviour though. Sure, you can learn things even from mean people, but those mean people could and should learn to express that "feedback" in a way that doesn't feel like sh*t for the recipient.
