I’m sure that there is a lot more to the story than what we as “outsiders” know. Now this is purely speculation on my part, but from what I studied in college, the marshal islander kid was probably bullied and called racist names all his life and when Preston called him that racial name, the marshal islander probably had just had enough and hit the kid, and when you have been holding in that much anger towards people who call you racially charged names all the time, you’re gonna black out and not realize how much harm you are inflicting on the person who is getting beat up. When kidsare constantly called names, they push it far down inside of themselves until one day there is no more room to push down all those hurt feelings and then you explode like a volcano. You either go crazy and shoot everyone who called you names constantly, you either kill yourself because you can’t take it anymore, or you snap and decide to teach the bully lesson. when you snap, you actually black out and don’t even realize how much damage you have caused until you are pulled away. I have noticed that kids who are bullied and have a good support system at home and strongly believe in a higher being are the ones that can take the bullyin because they know it won’t last forever.
