Not for me

Yes. People debate the same thing with the likes of Rise Against and AFI... They're Punk, they're all Punk, not Alternative.

um.

Pop punk is the best classification for them, I think.

And it's also one of my least favorite genres.

Pop Punk is pefectly fitting for Green Day, as in it's mixed with modern overproduced pop music. Pop Punk doesn't specify which kind of pop it has elements of, it just has elements of pop.

Early Blink 182 is pretty much a super poppy skate punk band.

Just because it's normal, watered down, overproduced and uninteresting doesn't mean it doesn't fit the term pop punk.

Rise Against are melodic hardcore, no doubt about it. Early AFI is punk too, no doubt about that.
A lot of of punks seem to go ''I don't like it, so it's not REAL punk''

And to clarify, I'm not the biggest fan of these bands either.

This way of posting is annoying.

I use "pop punk" for music that "would otherwise be punk"--it has a punk attitude to it, the basic punk feel, song structures, etc.--but it's extremely polished and slick in terms of production and musicianship, with pretty much all of the "rough edges" and significant quirks filed down/ironed out, including compositionally. You could think of it as "punk transformed into a safe and mass-marketable product for average Joe/middle Americans," or "punk that neatly fits next to John (Cougar) Mellencamp tunes on the radio in between Ford dealer commercials" (which isn't to rag on John (Cougar) Mellencamp)

I just relistened to Dookie, and they're a pop punk band before the more watered down version we see now a days. Just fun songs with sing songy choruses.

they play rock

Are you insinuating that I said that they're not a rock band?
