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

I was never bullied and was the popular kid, and honestly, I don’t like the concept that all these ‘nerds’ you see nowadays were bullied back in school and it’s why they became nerds, in fact, I never heard of school bullying outside of the US schools, or generally North Americans ones. Maybe movies contributed to that, or reinforced such a phenomenon?

Grew up in Germany in the 80/90s, we had plenty of bullying.

Nah, it's common everywhere. Kids can be cruel and some will be given the opportunity of access to someone not fitting in.

I was a nerd well before I was bullied. I remember some of the earliest bullying I experienced - this older kid called me "Macintosh" because we had a Mac computer at home (no DOS/Win) and this kid thought that was worthy of harassing me about. It was weird because that kid wasn't much of a computer-savvy person but just found something "different" to call out. /shrug
