I found this article to be mostly true. There is no need to get "angry" in most situations. I have found that narcissists get angry when anyone doesn't agree with their thinking. I do think that when people learn to understand their own emotions and where they stem from, it is quite easy to evolve and in most cases anger becomes obsolete. However, I do think that in circumstances of injustice, anger is necessary. Not to say that it justifies brutality but as a means to end brutality in all of its forms. Anger is a necessary tool to end exploitation. Exploitation of humans, animals, land, resources, the environment, war, etcera... I think that that is where anger should end. At the point of emotional response. The way it should be learned to be expressed is through constructive positive change in its corresponding issue. Acting out, brutally in anger is a fools game.
