Survivor,
Dissociating one's anger is common from child abuse trauma. Anger can become an "all or nothing" split, which I don't assume in your post, but which resonates with me. I hear "All Anger/No Anger" splitting, and hot or cold with anger ego states, not a complete integration of the emotion yet. But then I also hear the truth about seeing a traumatic situation from a non-emotional perspective, which I agree is part of healing from trauma (called "re-framing" or "neutralizing"). Seeing a situation from that non-emotional and rational perspective of deeper understanding is one way to neutralize a trauma memory to make it less toxic. That is what you appear to be talking about.
It sounds like you are in a phase in which it seems necessary to distance yourself from your angry child and integrate a more calm, rational adult perspective, and it sounds like you are gaining much awareness of the polarization and are working through it to find a place (the View from the Mountain Top) in which you have a higher perspective. This is fine to do and a part of healing and learning the handling of a particular emotion, anger.
But it doesn't follow that others need to be in this phase. This IS "your gift" today; it's yours. Some of us know what you are talking about from going through to that part of healing.
Your phrasing seems to push this perspective toward others, which people find too forcible. I have done this, often. I wonder if it's a kind of dissociating, saying "not me/not mine" but somehow the healing I'm doing is actually "yours" : here, let me heal you.
Remember that all healing is already cooperative and it's necessary to love the self and own it as your healing process. This is ALL about you, and that's okay to acknowledge. I agree with you up to the point at which you say this is not about you. That tells me this healing is not fully conscious yet. It's happening in the background. Please let your healing be just for you, as you are fully worth it.
Maybe journal it, take it into therapy, draw or paint it. Love it, create it.
You are worth the work; it doesn't have to help others yet. Don't make it about us yet. That will come later. (Hugs)
