Not enough facts here. These days the term bullying is frequently used in the education system for those who won’t affirm and embrace the homosexual lifestyle or otherwise offending snowflake adults.
The girl also said she had been bullied by bigger kids.
My thought as well. I’m guessing he made her walk only 1 of the days to teach the lesson and then drove her the other 4. Between that and posting her shame for the world to see I’m guessing that it got the point across.
That being said I’d love to know more about what the bullying was about. I’ve seen many cases where it was a defensive response to prevent harassment of the bullier from others.
