We had an interesting discussion about bullying at a seminar yesterday. It is a very slippery subject. Part of the problem being that "bullying" is a highly emotive word, and so even naming something that way is actually a fairly aggressive act.
One of the problems is that we often assume that bullying has some sort of logic about it. That is, that the bully employs the tactic in order to achieve something. (Of course in one sense we don't do anything unless there is some sort of "payoff"...but the payoff may be that we just enjoy seeing people squirm).
It is too easy to rename the bully as a victim when they may just be a prat!
