Seamus, I understand what you're saying, but just because one person's angry and nuts doesn't mean the other guy has to respond in kind. Often a rational solution (such as, in this case, making the event private), will frustrate a person who'd really like to 'zing' folks when their virtual blow misses its mark. So there might be more 'gotcha' points in an effective, peaceful solution that leaves no excuse for retaliation.
