I think this is a little touchy feel. The defining quality of humanity is reason. The extent to which some of our nationalists reject rationality is...depressing. I have little problems with spades being called spades, and trolls being labelled just that. In my rather crude way I don't see why those who mess up Wikipedia should not get what they merit.

The problem is that people react to rational criticism emotionally. When someone is told their behavior is inadequate for their integration into a society, they naturally act emotionally. The emotionally intelligent use their negative emotions to take positive action. But, more often than not, individuals that do not want to face their own inadequacies turn outward, insisting that the fault lies in the source of the criticism and not themselves... which leads to flaming, etc.
I, for one, don't bother to read a thread once it is clear that emotion has gotten involved... nothing gets truly resolved once rational thought is abandoned. The question is how do you teach people to step away until they've calmed down and can approach things with a clear mind? Until that happens, the vitriol will continue.
