> Physical violence is not a cure for any known disease.

Since when somebody disagreeing with you is a disease?

bluejekyll really should have said disorder.

If you have a kid who is getting bad grades in school and has behavioral issues, and the underlying cause of it is ADHD, then no amount of physical discipline, even up to child abuse like closed fist punches, throwing metal chairs, screaming at the top of your lungs while doing it, etc, is going to fix that. All it will do is breed resentment. And if you want to have a relationship with your child after they turn 18, I'd strongly recommend minimizing that.

And I'm speaking from personal experience as a child who went through that. My grades were as bad my senior year as they were from elementary school. The fear wasn't enough to make my brain neurons fire the same way as the other children around me.

(I also object to the labeling of anything that doesn't perfectly mesh with our conformist modern day upbringing as a 'disorder', but that's another topic. Given the realities of our system not adapting to the needs of people, but requiring people to adapt to the needs of the system, I'd reluctantly support medication over physical abuse.)

> then no amount of physical discipline, even up to child abuse

All physical discipline is child abuse. That's why it's illegal in most of Europe.

The obvious exploitation vector is deliberately pissing you off to make you feel guilty and lose confidence. I think my father used to be like you for the first two years or so, then he grew up :)

Setting bones? Fixing dislocated shoulders?

These are activities meant to do something else but the pain is a side-effect. These are actions of treatment. It's a stretch to call it 'violence'. "Force" is a word which comes to mind instead.
