On the personal side: Absolutely not! I am no saint, but doing EVERYTHING I can to control my anger.
My anger has caused me to be spiteful and horrible to the people I care about. An ex reached out to me- drunk text. He strung me along and we hooked up. I told the pregnant girlfriend he decided to NOT tell me about until after, all out of spite. I was pissed. I wanted to hurt him like he hurt me, had nothing to do with her or “doing what was right.” I feel so much regret letting my anger and jealousy go that far. Even if she does not believe me, which I truly hope she doesn’t. A kid is involved, my feelings do not matter. Anyways.
If it does not lead to positive change, all it does is make you hate yourself, hate others. You push people away, intentionally or not. It is a horrible feeling to be stuck in. You lash out and then hate yourself for being so horrible.
My father yelled and screamed my whole life. His anger caused my mom to be so depressed. My older siblings got a more “fun” version of her (they had a different dad). I got that too- but also the mom that cried on the couch telling me to never get married or trust men. The years I had to watch her go from being happy and creative to sad and depressed- she stopped taking care of herself. It is not ALL my dads fault, no one was stopping her from seeing a doctor… but yeah. I saw how his anger hurt her and made her cry. How his anger changed her. There is a version of my mom before she met my dad, and a version after. No marriage should have that much suffering, and I know she wasn’t perfect either, with her anger too. Nothing justifies his behavior, however. It was over the top.
None of that anger was for positive change. Positive changed was promised, never delivered.
He is now facing reality. And I know it is hurting him.
The only “positive change” is reality hitting hard.
Political, I cannot imagine it to be useful without positive change. It just is not. But, other people have commented on politics so I will refrain. I am offering an answer on the personal side mentioned in the question.
