you sure about your claim?

> According to Lee (2013), there are two leading causes of school shootings: bullying (87%), as well as both non-compliance and side effects from psychiatric drugs (12%). Most school shooters claimed or left evidence behind indicating that they were victims of severe and long-term bullying. The majority of bullying victims experienced feelings of humiliation, which resulted in thoughts of suicide or revenge (Lee, 2013).

Yes, I'm actually pretty sure. Peter Langman, a very well known expert on the matter, sees no clear connection between bullying and shooting, also points out that many shooters were bullies themselves and don't target their supposed offenders: https://schoolshooters.info/sites/default/files/bullying_sch...

It's interesting that you quote that shooters "claimed" and "experienced feelings" of being ostracized, because many of them do indeed feel that way, like Elliot Rodgers thinking of himself as a perfect gentleman passed over by women for some incomprehensible reason despite clearly not being one. The catch is that those feelings are not always rooted in reality: many of them were well-liked and popular. What they also often turn out to be, though, is "injustice collectors" who tend to hold grudges and refuse to take responsibility for their own shortcomings (including, I assume, their own contribution to being excluded by others), according to this FBI report: https://www.fbi.gov/file-repository/stats-services-publicati...

There was a Reddit thread in recent weeks about a related topic and there were a decent number of bullied males talking about how much they thought about shooting up their school. IMO, it's very possible that it's an intersection of bullied + having the means + propensity (for the most part, aggressive/aggrieved males).
