Some are, some are not. And btw, a real punk is a nihilist more than a rebel, mod were rebels, hippies too, but punkers just don't give a shit (so they say).
Hüsker Dü, Ramones, Gun Club and Cramps are my favourite. (CCCP too, an italian group)

Sex pistol were nihilstic, very much too. Ramones and Clash really aren't nihilistic... Clash were more rebels, and ramones is like the we see some fun in all the ****ed up shit around here...
clash also have that happy sound to their more ska like songs.
but, it's still real punk, not pop like Blink or Sum
