..And people wonder why I hate black people?
I doubt that's how it went down, it seems like a twisted overly exaggerated bedtime story his mommy tells him.
People in my school (Regardless of color, race, etc..) are territorial. They don't fuck with you unless you provoke them. Provoking can be several things such as: Having something they want, sitting in a place they claim is theres, saying something dumb, etc..
Blaming this on black people alone isn't fair, this is just one circumstance. I've personally been jumped by people of my own race and even (In one funny occasion) the "AZN Unit" ...damn that was a trip
