Haha! That post actually made me lol, Caliburn. It certainly cleared some things up! (just kidding, heh)
Stereotypes will always exist... It makes it easier for people to create a first impression. I myself dislike first impressions/stereotypes. Because most of the time, they're false.
In grade school I used to be the lonely guy, I had few social contacts and I was scared of girls (I know... >_<). People started picking on me. And well, it started to tick me off. Well after a few years of this BS I decided to change. I started talking with more people I didn't know and I quit playing the victim role. It did work, but sadly, I can't change the past.
Once you actually get to know the people that give you a certain title, they'll most likely change it. I really wish I could change the past... But alas, like I said, I can't.
Also, venting your anger onto those who pick on you only makes things worse. Believe me...
