Whats wrong with being trendy?????

Alot of people have this opinion that if you are into hip hop and or street fashions - that you are a ned/chav/hooligan etc without even knowing you - lets take for example - if i wore a henri lloyd jacket and wore a baseball cap - would that mean i am a nasty violent person??? no - cant a guy just wear labels without being judged? why do society hate chavs? not all young fashionable men are rude or violent - i certainly aint!
