Atreyu is a huge maybe for me

One more note, there is a bit of mention of Punk in all this talk. My take on it is that we are now (being IN metalcore) twice removed from Punk. Punk kindof spawned Hardcore, and thats a big Kindof (idealogically they are pretty different at their roots, nevertheless there is a lot of punk influence in hardcore, the big transition coming with bands like Bad Brains and Minor Threat). Hardcore spawned the "Core" in "metalcore" and Metal is obviously responsible for the "metal". Metal as a genre is so removed from Punk as far as roots go, that to call "Metalcore" a subgenre of either Metal, Hardcore, or Punk, isn't fully true. It's a blending of two very different styles (that sound the same to your parents), Metal and Hardcore. Now I'm done.

Hardcore isn't spawned from punk. Hardcore IS punk. All hardcore=punk. I don't know how many times I have to go through this with people. It is really quite annoying trying to explain to people that there is no such thing as a hardcore band that doesn't at least have an implied 'punk' after the term hardcore; ---> hardcore (punk). Granted New York styled hardcore bands are further removed from their punk roots than west coast hardcore bands, but they still have anti-authority lyrics and simplistic song structures (thus punk). I think the big misconception is derived from people calling early metalcore and bands like hatebreed hardcore. It created a rather nasty confusion.

Also, if my parents ever mistake Rise Against or Black Flag for metal, I'll kill them.

And Atreyu is not a metalcore band. At best Atreyu is an emocore band or just an emo band with metal influence.
