Much of Men's anger is developed by the way men are perceived in the world. Men have been thought that acting on their anger is masculine or manly (by society). So these same men, then express their anger however they see fit (fighting and yelling).
Men are more likely to express their anger with physical aggression, passive aggression, and impulsively dealing with their anger. Let's not forget they are more likely to have revenge motives and coerce people to agree with them.
Men, unlike most women, don't have to have a reason for their anger. Anger in many men is a behavior that has been developed over time. As men grow used to the behavior, it becomes part of their lifestyle, and problems will soon follow. Most men that have anger issues feel that there strong, abrasive behavior has helped them, more than hurt them. In reality, when they have time to look at their life they find that the people they care the most about are slowly pulling away. Unfortunately the only time the angry man takes a look at their life is when it is too late.
