I have a friend who strongly believes that venting anger for hours and hours about the same topics repeatedly is healthy and that good friends must tolerate it. I learned recently that it is a myth that venting anger is a productive solution to anger. In fact, I learned that it can be counterproductive and like adding gasoline to a fire. What might be the best way to demonstrate this fact to my friend because simply telling him that fact does not really convince him. He claims that venting anger makes him feel better. He is not very open to even questioning whether or not that is true. Any suggestions would be greatly appreciated. Thank you.
