Yes, punk is a form of protest. Drunks protest against society through their antisocial behavior and appearance. I believe they don't even know what they want, and their methods are wrong, but they are punks. As for who else could be called punks, I don't know.
So you fall at his feet hes the one who betrays you
Its the servants devotion for the decay
Stand up
There are no flowers on your grave
There are no chains
There I keep chanting for the forgotten name © Amorphis
