What is a good, healthy, unhurtful, socially positive way to express anger?
Racism, sexism and all the various other "hate these people" isms and phobias are arguably methods for expressing and rationalizing anger. And they're bad. But what's a good way?
I remove myself from the situation that caused the anger.
I let myself live the anger for a minute or two, or a bit more if needed.
When the anger is gone, I identify what emotion is the cause of anger. Anger is 99% a reaction to a negative emotion.
I say outloud to myself the reason of my anger. Otherwise, I feel like the anger is pent-up.
If my anger was directed at someone, I apologize and explain why I was angry.
Finally, I reflect on the situation and the emotions I experienced. Sometimes it's 30 seconds, sometimes it's a few days, depending on the gravity of the situation. By understanding what caused the negative emotions, I can handle it better in the future.
