Maria, same as all the other emotional responses, anger is inflexible and irrational. I agree that if we are angry, it would be unhealthy and damaging to suppress or hide it instead of working around of it.

But on the other side — do we need to have this anger in the first place?!

We are much better and much more effective in setting up our boundaries and protecting our values in a clear and calm state of mind. By the way, most of the “values” we are protecting in an angry state are imaginary and have nothing to do with our higher self.

In my opinion, your point #3 is a complete stretch — we are much more efficient at transmitting knowledge when we are calm and aware of the other people states. When we start shouting at them most of them would stop listening and will start to defend their views, positions and status. Yes, sometimes it works if you are generally a calm person — shouting might draw attention to some very important point. And this trick is still much better when executed calmly and reasonably.

As for relationships — anger creates animosity, conflict and damage unless handled very carefully. But this handling of anger is a skill which 90% of people don’t possess.

So, while I agree that “if you feel it you should not deny it, but acknowledge and accept”, I think there is no valid reason for the desire to feel it in the first place.
