This may have happened a while back, but when I was a student at NYU Tisch School of the Arts, I was quite an expresser of opinions. On one occasion, a white boy got so mad at my freedom of speech that he punched me in the back of the head. Like a civil person, I tried to ask the professor, Laszlo Santha, to call security but he laughed in my face and told me that "it was a joke". In response to that, I slugged the white boy in the face three times, saying I was being a comedian.
This was not the only case where I have had altercations with whites. Some italian dip[expletive] in college once tried to start a fight with me after I made a minor comment about the fact that Osama Bin Laden is not a coward. He started whimpering when I called the police on his arse. Unfortunately, since I am Chinese, the police did not take it seriously and simply let him go. They called his death threat a joke.
Also, in high school when I was 14, one italian guy kept singing my name and threatening to beat me up with his "superior martial arts skills." I punched him in the face. He went crying to the dean. I kid you not.
When I was 15, a redheaded white slut put her feet up on my chair. I asked her politely to take them off, but she kicked me. I punched her in the face right in front of her friends. In response, she sent six of her boyfriends out to beat me up, which they did, but I still take it as a compliment. Am I so frightening that she needed six guys to take me down?
This one white guy once pushed my mother right in front of me on the bus. I grabbed him by his fat throat and slammed his [expletive]ing head into a metal bar. My mother then kicked him in the back of the head.
The point of all this is that you should not be afraid to use violence against crackers unless of course there are police around the area. I am only an average size male, 5 foot 7 inches, and even I managed to beat these guys up; some of which were well over 6 feet.
