I never said this. Being bullied, assaulted or sexually harassed never justifies a shooting. It's still understandable people snap. (Like psychologically, you know... not in the sense of suggestions... what a clown mind do you have?)
If you don't understand this, or try to misinterpret my comments, you behave like the Bullies... which tells me a lot about you.
There is never any justification for a shooting but there certainly is a cause. Kids don't just randomly develop the urge to kill their fellow classmates.
