Again, it's the media influencing things and blowing them up to almost iconic status. In never ignoring the attitudes and values it detests, and deciding to make it into a big issue, the media is actually encouraging "wannabe rebels" to automatically find a culture worth being part of, in order to rebel against society's values.

Seriously, the same works with all "sub-cultures" and the like; if the media stopped reporting how bad hip hop fashion was, for instance, I bet we'd see a lot less people adhering to it.
