Bullying exists outside of white middle America. I went to school in Baltimore for a time and there were plenty of bullies. One day as I was waiting for the bus one of the other kids decided that they were going to run back and forth and slap me in the face as they ran past because they didn't like me, had a kid threaten to kill me and constantly tried to attack me on my way home from the bus stop. It was bad enough that my mother found a new job and moved us elsewhere.

When I lived in Japan some jackass took my school shoes from the shelf. I don't know what I did to them, but they clearly didn't like something I did so in the most passive aggressive thing they could do, they fucked with me. The teachers didn't give a damn, just told me to wear shoes that were like half my size. Culturally Japan has had severe bullying issues that became a very public conscious debate in the 2010s where multiple high profile deaths of students from bullying occurred because the bullying was horrific and teachers would tacitly endorse it.
