This song ISN'T aimed at teachers, peers or parents. It's about conformity as a whole; its about not being a manipulated, mindless drone and having some control over who you are. A few swear words do not make a disgusting song.

I'd be far more concerned if my child were to sing lyrics to a song about threesomes or one night stands (check the charts, they're there). I'll admit I like these songs, and these lyrics dont bother me, but why don't people have as big a problem with these?

"It's disgusting cos it's like metal and that innit?"

Because most people don't pay any attention to what they're listening to.
