I don't get angry. I haven't gotten angry in ten years. A Buddhist would say I have "pulled up anger by the roots".
Anger is predicated on the desire to hurt someone. The desire to hurt someone as a terminal value is pure evil.
I have been on the receiving end of a lot of anger. Ostensibly, it is because of things I did or I didn't do. None of that matters. How often a particular person gets angry at me has little to do with me and everything to do with that person.
Though I no longer get angry, I do feel stress. My baseline stress is a function of physical exercise, social interaction, food, meditation and art. But that's not goes through my head. When I feel stress, I go looking for something I'm doing wrong like an appointment I've forgotten about, a chore I've been putting off or some other personal inadequacy. I misattribute the stress to a confabulation and then go about solving the wrong problem.
I think angry people do the same thing. They feel anger before identifying a target. This would explain why observation that whether someone gets angry at me in a particular interaction correlates with how frequently that person has gotten angry at me in the past and cannot be predicted by my proximate influence.
With particularly angry people, I can predict when they will get angry before they do but I cannot predict what they will get angry at. Except that, if I am alone with the person, the target will eventually become me no matter what I do.

―100 Tips for a Better Life by Ideopunk
When I was a kid I had an adult berate me for not shoveling dirt into a hole and then, an hour later, berate me for shoveling dirt into the hole. Neither beratement had anything to do with the task. He just wanted to make me suffer. But he didn't understand his own motivation. He confabulated that I was a lazy kid who should have known better than than to do (or not do) whatever I was doing (or not doing).
The most undeserving victims of anger are the victims of genocides and such. But in my personal experience, the people for whom anger causes the most suffering are angry people themselves. Anger is incompatible with happiness. If you are frequently angry then you are frequently unhappy.
Pulling up anger by the roots makes you a gentler, happier person. The catch is that anger is a natural defense against other angry people. To safely remove a natural defense you must replace it with an artificial one.
If you are not an angry person then the best way to deal with angry people is to avoid them. If you cannot avoid angry people then distance yourself from them. If you bump into angry people then diffuse the situation. If you cannot diffuse the situation then fight as a last resort.
I largely agree that anger and emotional happiness (but not ultimate Happiness) are quite incompatible, doing 1200 hours of meditation over two years has reduced both the frequency and half-life of any anger I feel and it made me realise just how unpleasant it actually was. However, let me try to steelman anger:
First, very advanced meditators actually seem to report that even moments of anger are "perfect" in some way, just like all other moments. I've certainly seen Shinzen Young and other zen masters get somewhat angry, not at anyone, but to emphasise a particular point in an emotional way. So anger is certainly useful for communicating your values to an audience. Hearing someone say "I really care about this" in a neutral tone doesn't quite have the punch of someone getting mildly angry.
There also seems to be a relationship between anger and a sort of aggressive motivation. I notice that my bench press sets seem a lot easier if I get angry first, and they're also a lot more pleasant, being angry without doing anything is unpleasant, but expending that "angry energy" towards a goal does seem to be pleasant. Being angry about things like the existence of cancer can certainly help with motivation to solve these problems.
When I watch the speeches of Martin Luther King Jr, I am inspired by his total absence of anger. Perhaps he is a saint, in which case I endeavor to follow his example.
