Anger Management

People consider anger is a bad management and wrong quality of a person.No,it is a fallacy.I can tell with my full wisdom that it is good and bad.Anger in a wrong circumstance for right reason is quite benevolent for society and human being. For example,in a professioal environment,if anyone raises his alarm by showing anger for in-suboardination and sexual harrament against female workers/employees,it is not all a discouraging phenomenon. As per me, anger management shoule be divided in two categories, positive and negative.It is somewhat like positive thinking and negative thinking. Though positive thinking is always recognized, but that does not mean that negative thinking is absolutely detrimental. If anyone expresses negative anger and outbursts on someone for not a very valid reason,then it is definitely bad.But,flatly condemning anger management is bad.I can not digest. What is your opinion because I would like to debate on this subject.
