Maybe Gary, anything is possible. I firmly believe in personality types however and consider myself a direct personality. I call things as I see them and usually will not sugar coat much. Passive folks mistake that as anger where it's just being direct and to the point without emotion.
Now on the West Coast, people are more relaxed and less direct so they will usually take affront to that kind of communication. East coasters are very much direct personality types and I think as a Californian you may view everyone in the Boston or NY area as needing anger management classes. As a young man I made a good living in B2B tech sales by developing a respectable client base in NY, NJ and Boston and I did that by relating to them.
Personally I think the people that need anger management are the ones that can't stop from hitting women, beating their children, committing assault, battery, shooting people and so on and so forth...they don't have control. Myself, I'm all about control and it's amazing how much controlled anger can be used as a motivator.
The things that one can accomplish because they are fueled by anger, focused and directed by it. The obstacles that can be hurdled, the trials and tribulations overcome by that fuel. The energy that can be generated by it. It's OK to be angry, I think more people on these forums should be pissed off myself, just controlled. That's what a good anger management class should teach you... how to be angry, just control it...keep it "managed". I think if everyone was in a Zen state of "peace" totally void of anger, nothing would ever be accomplished.

Love ya Gary...
