That's fine for learning to get along. Many relationships are antagonistic though, and dealing with a bully in school can help with dealing with an abusive spouse/family member/boss/colleague later in life etc. There are bullies in adult life too, they're just more subtle.

I'm sure that many people have learnt to deal with bullies that way. Fair enough, and everyone should make the best of whatever environment he finds himself in. But it would be a mistake to think, as people often do, that one's own historical path represents the best path for all.

For one thing, setting aside how cruel it is, at 12 years+ the 'school bully learning method' is monstrously inefficient.

Btw, similar arguments are applied to most school subjects. For example, one is forced to take obsolete subject X because it is useful if one later wishes to study subject Y, which is in turn can be helpful if Z crops up in adult life, and so on.

Most sane adults would rather learn 'just in time' and to the precision and extent appropriate to the unique challenge they face. Yet, perhaps because of the enormous sunk cost of their own schooling, they become irrational about this where their children are concerned.
