Anger is also a natural part of being human ... like sadness and fear ... and we should not be angry about sometimes getting a little angry (or sad about sometimes being sad, etc.). That's just how our animal brains are wired.
HOWEVER, unlike sadness (which is just part of the scenery of life, rainy days following sunny), or fear (which may even serve to keep us safe and out of harm's way if held in moderation) ... anger is truly fire & TNT, and has potential to do great harm. It is more likely to end up as a fight in a bar, a broken relationship or starting a war than it is to do any positive good. As well, there are other emotions and perspective which can accomplish the positive goods more effectively.
So, for example, calm reflection, looking for a constructive solution and keeping one's head as much as possible while taking effective action is an approach more likely to solve a problem in this world or in one's life than tossing more fuel on the fires of hate. ... Perhaps, "righteous indignation" or "tough love" (if a parent ... even the Zen Master's "30 blows" are more of this kind) or "a firm hand with a calm mind" may be justified by a situation ...
... but I would say that anger is rarely, if ever, an appropriate response.
We discuss the subject more during out study study of the Jukai Precepts ...
