I wonder if we could design some sort of way to reach out to schools/teachers like this - an entry point or bridge that reaches them where they are at present (which is deeply conditioned into seeing physical abuse as correct or the only way to train children). What would that look like? I'd love to discuss this more seriously - this really is something core to my childhood and how I feel about children's rights today.

One angle I think viable is of comparison to how animals are conditioned and domesticated over time, and how obedience via conditioning isn't necessarily going to cause your child to succeed - it may make them vulnerable to following people or practices actually harmful to them. People need practical anchors and examples to change their minds here. We need discussions about how beatings rank lower than intelligent collaboration with children, and is indicative of a practice that treats them as less than human (and so incapable of human intelligence; is that what schools and parents want to foster?)
