This reads well-meaning, but ultimately misdirected. There is no solid data corroborating the "school shooters are bullied" narrative - in fact, many of them have a long history of being bullies themselves, which then gets twisted from "kids try to avoid the weird kid who does disturbing things" into "poor little baby had no friends".
Disabled, queer, poor teens are not shooting up schools. The profile of a school shooter is overwhelmingly white, male and middle/upper class. A shooting is an ultimate tantrum for which the perpetrator is never held accountable.
