Finally a new and interesting topic for discusion.
Labeling definately promotes segregation and discrimination among teens. it also seems that the further your specific subculture gets from the mainstream, the more easily it is to be discriminated against by older generations. it seems that there are more groups to classify people as. my mother grew up in the 50's and 60's, and she frequently tells me that i label people too much, yet there are more labels now then when i was in high school in the early 90's. goth was just starting to become popular when i left school, and i never met an emo. in my highschool, the cliques were something like: rockers, mods, jocks, populars, cowboys, nerds(smart), dorks(not smart, but still nerdish), chol(o/a)s, and the various ethnic groups too various to mention individualy. I was mostly a rocker, but i could easily move between most of the other cliques with out trouble(populars were most likely to discriminate).
as for the criminalistic aspect, i was quite a criminal in my teens. the usual: vandalism, theft, burglary, assult, possesion of controled substances. i was only caught a few times, but i was told, each time, that i would end up in prison or dead by the time i was 21(or some variation of that theme). i was arrested a few times, but i never spent more than the max 72hrs in the main jail(the only thing you should ever say to a cop is: ' I want a lawyer') . now, in my thirties, i have settled down and squared up somewhat, but not entirely. i still have my long hair and unique facial hair. i wear mostly work clothes like dickies and ben davis, and get followed around by security guards when ever i go into large chain stores. i had a friend who was fired for "theft", though really it was because he had a mohawk and was far from mainstream(proof is lack of posecution).
over all, i think it depends on the individual.
