Wait wait - so he knowingly violated all social norms, despite gentle attempts to correct him, and that proves there is an ugly side to fantasyland? It would have been more interesting if he had done something non-mainstream that did not impact on other players and seen if it would have gotten any abuse.
After all this is the essence of tolerance in real life - nobody expects you to be tolerant towards people who are shooting you; tolerance comes from a "live and let live" approach. Investigating the equivalent of that online would have been interesting, but it is not what he did here.
What he did here was the equivalent of say, farting in your face because it is "within the rules" (i.e. not illegal) and then act surprised when this made him socially excluded.
