First of all, if you say "the sex pistols are real punk" you obviously know very little about punk rock. The sex pistols were merely a band that was brought together for shock purposes to make money. Punk was originally founded on a rock and roll beat with the Ramones, the Clash and others. Hard-core punk was invented with Black flag and Husker Du. Saying a commercial band like the sex pistols are punk is as ridiculous as saying Green Day is punk.
