Treating bullying as everyone's problem reduces incidence in primary schools

I always found it really frustrating that a "zero tolerance" policy to bullying seemed to disproportionately affect people who eventually fight back.

I would guess it's a combination of "nobody sees the first hit" (since your attention is elsewhere, of course) and that bullies get quite good at testing boundaries and thus know how to avoid detection.

But, really, it's truly frustrating that as I child I was bullied relentlessly, and when I finally took my parents advice and stood my ground, I was expelled from school (due to zero tolerance). Those bullies continued to torment some other kids, of course.

This is far from an uncommon situation, over the years I've heard many more scenarios like this.

Wow, expelled seems very harsh.

I know when i was a kid we would get suspended for a few days if we had a fight. Banning a kid from that school for life seem pretty harsh.
