What is anger?  Can it ever be of use?  Anger on own behalf can be self destructive.  Yet righteous anger can be the prompt to ensure that we do what we can to right the wrongs of those with out a voice.  Christ was a voice for the poor and the exploited.  Yet when he was accused he remained silent even though he could call on an army of Angels to come to His aid.  Anger is a tool   to be used with care not as an excuse for violence and hatred but to bring salvation.
