Punk Help?

I have a problem I love punk but I can never seem to stay away from the mainstream punk, don't get me wrong I love those bands but I really f**king hate being in the mainstream, could somebody give me some recomendations. As it stands I like Green Day, The Offspring, Franz Ferdinand, and Good Charlotte (there're a couple others I can't think of). Also there are two less mainstream bands I like and those are Rancid and Bad Religion, but those aren't far off the beaten path. Any help would be most appreciated.

Radio Science.
Rocket Birdmen.
Both went off at the metro the other week.

Who the fuck cares if its mainstream or not?

If it sounds good, whats wrong with it?

none of those bands you named are punk except for bad religion 25 years ago

rancid is punk, don't kid yourself.

the rest...eh. Good Charlotte is pop punk, green day is half alternative half punk, Offspring are more alternative now, Franz is like...garage.
