Okay, I get that it's trying to point out at generalization or whatever, but isn't punk rebellious by definition? Thought it was more about anarchist ideology and not just listening to music and dressing like a teenager.

Okay real talk, unless you rebel you are not punk. It's literally within definition of that subculture. Just wearing clothes and listening to the music does not qualify you for it.
Also, to the person that dyes her hair, OF COURSE YOU SEEK ATTENTION, no one dyes their hair if they didn't want others to notice! Honestly, I don't see why such people are afraid to say they want others' attention
