I can only suggest that you need to listen to some of those bands - I see a lot of similarities.
Edison Glass, Blindside, Dead Poetic, TBS, We Are the Ocean all jump out at me when I look at your list of examples.
Especially Edison Glass, holy shit.
To summarize: chill out, dude.
I'm "chill." It was a genuine question. They themselves would never even call it that. Can a band not blend pop/rock/punk without being called so?

Edit: I can hear the Edison Glass comparison though
