It's hard to call it bullying because in the natural order of the universe the strong devour the weak. But whether you believe in the Biblical concept of Man's dominion over nature or not, the key is that we are certainly different from the environment.
As a younger kid in elementary school I remember a boy named Kevin who pretty much ran our grade. He was young and handsome and smart and clever so he had first choice over a great many things. Teachers loved him. Students feared him.
I hated him. Not because I was his polar opposite, which I was, but because he represented everything that was wrong with the world. Playing to favorites. Running over the weak. Hurt for no reason. Anguish. Greed. Negligence. Rampant selfishness. Yeah, I hated him. A lot.
Now I get to use my mind and my charm to crush my detractors. Most times I don't even have to do the fighting. It's a special gift I've received in my wit that I use, with everything else I got, to protect those who cannot protect themselves and level the playing fields against those who would be less than human to endlessly indulge their own selfish whims...*stepping off soapbox*
Man I can get preachy. Regardless, this video makes me feel a lot better about things knowing that this kid, maybe for the first time in his life, stood up for himself.
