I've written about anger management before -- a particular important posting in the history of the VOI for my own reasons. Baizura sent me an email today; it spoke of the Prophet's will just before he passed away: one of the things he asked of Muslims was that we control our anger. A particularly poignant lesson considering how much anger there is in the Muslim world today, some of it justified but much of it not.
The Prophet Muhammad (pbuh) was not a pacifist -- he knew when to fight a good fight. But, in his Wisdom, i think he rightly identified one of mankind's largest flaws: our inability to keep our emotions in check. And the most destructive emotion we have is "anger". Its only purpose is destruction, pain and chaos.
