Gee, that's funny, cuz in a lot of people's minds, it was about rebellion against a corrupt system through mercenary tactics.
Mercenary tactics? What?

It was about learning to think for yourself, have your own sense of identity, to be who you are regardless of outside circumstances.
My experience with punk rock tells me it's more about conforming to left wing politics than it is any of those things you mentioned.

"we love music, it's a great way to get money and chicks and drugs," and Pete Townshend got pissed off at them, because he felt they'd completely missed the point of what they were doing, and started yelling at them
hahaha I bought a "shirt" (two cheap pieces of fabric stitched together) at a sex pistols concert years ago for $50.

The sex pistols are hilarious. Almost all of their songs were written by the first bass player, Glenn Matlock, who they kicked out for being too poppy and mainstream and liking the Beatles. They replaced him with Sid Vicious, ceased to produce listenable music, spiraled out of control and then ceased to be a band. It's the most punk rock story ever told.

I personally was big into The Ramones.
The Ramones win first prize in the "writing the same song over and over again" contest.

All of my hate aside, the Dead Kennedys are one of the best bands in all of rock music.
