D-Sel makes the point that Vernon Forrest's kid was in the car when these disgusting thugs tried to carjack him. That explains a lot about his aggressive response. The worst part of these sorts of incidents is you see yourself in them. People who make threats, in the presence of your child, will turn you into a different person.
This, for me, has always been a scary thought.
A few years back, I took my son to see Howl's Moving Castle down at Lincoln Square. There was a big crowd coming out, and trying to move down the escalators. My son, all of four at the time, was a little slow getting off, and an exasperated woman pushed him. You can imagine how it went from there.
The worst part, for me, was not the woman putting her hands on Samori, but some random dude who leaped in to defend her. There was a lot going on there. Rightly or wrongly, I think I perceived a racial element--the dude was white, and the woman was white, and here I am on the Upper West Side in a shouting match with her. I think I felt like he was jumping in on some Tarzan saving Jane shit, unaware that I was, from my perspective, trying to protect my son. We exchanged heated words, and as he got closer to me, I shoved him.
