Hey @TheVorticon

Been a long time.
@Former-Member 's 2 approaches interesting. I have done both.
I have been both disconnected from anger and flooded with it.
My siblings struggled with anger too, flailing around with it, sometimes hurting me, cos I happened to be close, but then turning it inward and finally both completing suicide.
It was a huge and long and very distressing journbey into the core of anger.
I also see it as part of my life energy, and work hard to make the most of it in productive ways. Sometimes its too consuming and I need to burn it off physically, and yes walking, running and pacing can help. Also being calm and learning to relax and feel through it, and deal with all the thoughts that flow. I have done a lot of meditation. Now as I am older, I can redirect it more easily.
I have had thoughts of revenge, but mostly I can work through actually doing anything vengeful.
Outrage has a purpose. Some people are good at venting it in socially acceptable ways.
The worst I got was repeatedly coming back to similar thoughts/themes but with different objects to whom my anger was directed. Mind you all my anger has had good reason so I dont think of it as irrational, and agree with @Former-Member . Psychological theories about directing it at the source can help but often life does not allow us. Eg my anger at families who damaged my siblings and my children's early life. I came up with an idea to make it physical so not stay in endlessly looping thoughts ... and bought a bottle of tomato sauce.... which sits in my pantry. I hate tomato sauce ... for me it is a symbol of bloodshed .... and how I would like to spray it on whoever is getting me upset .... then when I see it ... sitting there from time to time ... I can actually laugh at myself ... at how mad I can get ... but it has stopped me doing things that would ... escalate ... and get me in serious trouble
Maybe find a way for you to symbolise and validate your own anger .... without totally dismissing it .... give it meaning ... but not act out mindlessly ...
For most of my early life I was so disconnected from anger I was taught to belt a beanbag with a baseball bat ... that did not seem right ... and I found myself in a postion of pleasing therpaist ... so in end I stopped all that ... and found my own way ... but lesson learned ... it took a couple more decades for me to read ... all the neuroscience on it ... the cascades of emotion etc ....
Some thoughts can feed anger ... and make it grow unnecessarily ... thats only good when going into real battle ... My mother and father both experienced WWII. I am fortunate not to have endured that kind of thing.
