1) If you're roughly evenly matched, you should fight
2) If you're not, your peers should intervene - "pick on someone your own size"
3) If this doesn't work, escalate to older peers
4) If that doesn't work, escalate to adults
This relies on children being taught and encouraged to intervene in unfair conflict, which the research indicates they are naturally inclined to do.
I'm suggesting that the current "zero tolerance" approach practiced in North America does more harm than good by halting this process before it can resolve conflict - thus harming both the bullied and the bully.
So in rural areas if a child in school grabs another child, throws them on the ground, and starts beating them in the middle of math class, the teacher will not attempt to intervene?
Sorry but I don't believe this.
