Interesting and thoughtful essay thanks.
Is this a fair summary?
Your assumptions- "violence of any kind simply works."
- violence is built in -"not learned behaviour. It to at least some extent is built in, almost certainly in us as well."
- "bullying is at all levels of organizations right down to the individual."
Your answers- Overreaction works "Just as in the wild animal world physical contests within a species are primarily bluff and bravado, where death is rare,"
- Be prepared anyway "Fortunately my Dad had taught me defensive fighting"
- Non violence works too "Mahatma Gandhi and his non-violent successes both individually and in thwarting the entire British Empire and that gives me great hope"
- Look to yourself first "Be the change we want to see in the World", (Currently my email signature quote!)
Let me have a think.

( I have raised thousands of kittens and managed to teach them all to share and be loving to all. I had a three - four year waiting list for them.)
