First of all, let me say that I think bullies are some of the weakest people on the earth. They prey on the weak, the peaceful, and the gentle because they know that they won't fight back. I think it's deplorable. Kids who do it have some serious problems, and society just tells them that it's okay. I think all violence is deplorable, but lest we forget, there comes a time when defending yourself does more good than bad, and can become a necessity. This bully obviously had done this before, and had been successful. Somehow in his mind, he had come to the conclusion that he was bigger and stronger than another boy 3 times his size. Probably from bullying him before, and getting no response. The bullied kid did the right thing in taking the first hit. I applaud him for letting the bully attempt to hit him multiple times, and attempt to block the attacks. Finally, he quickly and efficiently puts the attacker in his place and reminds him where he stands...at the bottom of the heap.
Now, a personal experience with bullying. I was in junior high, and I rode the bus every day. I was relatively tall (5"10" in 9th grade), but I weighed about 90 lbs. I was all skin and bone. One of my best friends and I would sit in the back together every day on the way home from school, which in the mind of another kid on the bus somehow meant we were gay. He was a year younger than me, shorter, but a little heavier. He and another kid would sit in the seats in front of us and taunt us the entire way to and from school every day. Now, I have two older sisters that absolutely loved to bug their younger brother (I'm sure I did the same thing to them), so I was used to the constant taunting. I feel like I'm pretty thick skinned. So for months, we just took it in stride, and tried to ignore them. The bus driver, Janie, saw all of it and would try to get them to stop, but they just wouldn't. One day, I was getting off the bus in front of my house, after a ride of taunting, ridiculing, and as I passed this kid, he shoved me from behind, making me stumble. I quickly got up, turned around, and stared at him. He sat up a little straighter, as I looked at him, and he snarled, "What!?" Every part of me wanted to take him down right then and there. But I was always taught to turn the other cheek. So I did. As I turned away and took a step down the aisle, he jumped up and yelled at me, "Faggot!" That's when I snapped, if you could call it that. I quickly wheeled around, pulled my fist back, and gave him a swift and hard punch right between the eyes, bending his glasses and bloodying his nose. He immediately reeled back screaming in pain, and I slowly turned around, walked down the aisle, and got off the bus. The bus driver said to me as I left, "You shouldn't have done that. But I don't think he'll bother you anymore." He didn't. He didn't have his parents call the Principal. There was no suspension, and there was no legal problems. It was two kids working things out, and being allowed to do so. In fact, from that day on, he was a little nicer to me, and eventually, we were in some of the same classes in high school, and became decent friends. I respect him for who he became.
I've never held any animosity towards him, and I don't think he has towards me. We solved the problem right then and there, quickly and effectively, and we moved on. Yes, violence is wrong. Bullying is wrong and deplorable, and is a real issue. Not every situation is like mine. But this example and the example in the video point to one problem that we have created for ourselves - the removal of consequences from our actions. This bully truly believed that he could punch this kid at will. He knew that he would not be held accountable for his actions. So he acted with that knowledge. If he knew that if he tried to punch this bigger kid, he'd get pummeled, he probably wouldn't do it.
Just like that we have created a society where we prevent people from having to deal with the consequences of their actions. We reward bad behaviors by shielding people from the bad consequences. I believe that we will find that our society will begin to heal itself of so many maladies that it is plagued by today if we allow the idea of "reap what you sow", or "you get what you deserve" to actually be practiced.
After this incident, I don't think the bully will be bullying anymore, and I don't think that the bullied kid will get bullied anymore. On the one hand, the bully learned that maybe, just maybe, he should be nicer to others, and the bullied kid learned that he can be in control of his own destiny, and gained a bit of confidence in himself.
But that's just my opinion.
