Your thoughts on this?

Obviously, your son hasn't healed yet, either physically or psychologically from what he went through. How come you haven't taken him to see the doctor, and gotten him into therapy, so that he can work through his feelings in a constructive way?

Bullying is NOT A NORMAL PART of growing up. And the more people like you try to ignore it or pretend that it is, the worse it gets. Kids like your son are crying out for HELP when they say things like this. And your son isn't so young that he couldn't participate in something like a school shooting, if the opportunity presented itself. After all, the two boys who were the shooters in the Jonesboro, Arkansas shooting in 1998 were just 11 and 13 years old at the time of their crimes. Their motivation was revenge too- revenge for months and in one case YEARS of mistreatment and bullying by their peers. They killed 4 of their classmates and a teacher, and wounded 10 other people. And this particular shooting happened a full year BEFORE Columbine did. Your son is more or less the same age as those boys, and it sounds like he's going through the same kind of HELL that they did. My question to you is, WHAT are YOU going to do to put a stop to it??

Sounds like this should have been addressed when it happened.

And EVERY child has been bullied but we just sucked it up and moved on

Sounds like your son is or was enraged
