I read this blog from you with great joy and interest! I am quite of the notion that anger is not an emotion to be suppressed or sent away. The feeling of anger cannot be avoided, it just comes over you. I think it's human and therefore you can notice the anger in a situation and learn to deal with it accordingly.
Regarding Freud, I would assume the first part to be true, that depression can also mean the suppression of anger (among other things), but not the second part to let it loose on others. I also believe that this has laid a very big misunderstanding over the 20th century and continues to this day.
From a Buddhist point of view, one cannot fight anger, but only use it in the moment of its inevitable emergence for learning from self-awareness. When anger arises, it is a great opportunity to practice letting go!
So you could shout inwardly "Hurray!" as soon as the anger comes and you say: "An extremely good opportunity to practice letting go! Life gives you the opportunity to exercise again and again. Because if it didn't, how could we even learn to practice with negative thoughts and feelings?
(Just imagine, you every time are "hurraying" when you feel anger. Would be curious how this would change one over time ... I guess this is what the Buddhists mean when they talk about enlightenment. People take their own sufferings lightly.)
If you compare it with the fact that you need a practice area if you want to learn to play football, you need a goal that you can aim at. Every miss is a learning experience. Without the pitch and without the goal and the keeper there is no opportunity to practice. My mind offers this place every day.
But, guess what? Other people have free will and often act in ways that aren't to our liking. Just as we don't always behave in a manner that constantly pleases others.
That I find a very important message. Especially because we know that we ourselves have not always been friendly and generous in our lives and probably won't always be, it would be good that our missteps would be taken with care by our fellow men. It is logical to allow others to do the same.
