Caution, for some reason you really just aren't getting that it's not difficult to change the stereotype on you, dress formal, simple, you are automatically exempt from it. Don't do the things they criticize in pubic, don't wear the clothes they criticize against. If you won't change then shut up, you obviously don't care about it if you are willing to stay the way you are. If you dress proper I'm certain they won't go "Oh, there goes one of those hoodlums". It's like complaining that your van is being stereotyped as a "creeper" van although it says free candy on the side and all of these inviting toys to tempt little kids, it's stupid.
