I see in many posts that anger is not a good thing to have, but I would like to ask, are there different types of anger or are all anger bad? Because in psychology, they talk about positive and negative anger.
Listen to what your psychology textbook tells you.
Not all anger is bad.
Interesting question but i can't really give you a good answer
Maybe this will helps..

There is no such thing as positive anger, just as there is no such thing as humane killing.
Although some examples of 'positive' anger has lead to creation of groups that bring about the end of unrighteous suppression, the emotion of anger in itself is negative in nature. Say for example some animal rights group have a noble cause to help animals, but sometimes their actions to support their campaigns are violent and besides causing others distress, their hearts are too not at peace due to anger towards people who mistreats animals.
Anger is one of the emotions in the seven emotions - Joy, anger, grief, fear, love, aversion and desire. These emotions affect us and our minds cannot settle and be peaceful.
just as there is no such thing as 'white lie' cos its still a lie.
