Why do I feel like people want to hurt me?

Whenever someone remarks about or mentions my chest and back hair I instantly get very defensive, angry, and on the verge of a direct confrontation. Since I was teenager my peers (no matter what the age) have said bad things and have made jokes about my biological predisposition. One of the reasons I spent most of my youth inside of a gym was because I thought no one would insult me if I were strong. That didn't happen, the strong part did but, not the insult part. I don't know how to get rid of this reaction to simple teasing. Just thinking about the social inequalities I have to face in my life, not only saddens me, but sturrs feelings of resentment, persecution, straight up discrimination. That is ok right? To be discriminated against because I'm white? Because of my heritage it is ok to be little me? The worst part is I can't do anything about it, if I try to talk to someone about why they insult me, I get nowhere. You can't talk to people about it. I have been growing up thinking it is a fact of life that I have to act differently and be treated differently because of what is under my shirt. Maybe that is why I am so goal oriented. The only answer the media presents is make money and all my problems will be removed. Is this true?
