Quote from Jasta,

"In Connecticut in 1993 people considered Quicksand hardcore and I'm thinking ‘no way this is indie rock.' We wanted simple songs with simple song structures. All out brutality, 30 seconds and it is done."

I challenge you to find me one 30 second Hatebreed song.

ok i would call them new school hardcore. and the other bands i mentioned also

Infest

Don't make up genre names. They are metalcore.

WTF?

no.noway

They're metalcore for jocks. Get over it. Your favorite "hardcore" band wants to push you into a locker and call you a faggot.

i listen also a lil bit to metalcore, not much cause i dont like it that much but i still do, and i dont really think that hatebreed is hardcore then.cause they do shouting, and so it nearly cant be metalcore. i would more call it a mix of hardcore and metalcore, but still i would call it hardcore, and nearly all of the metalcommunity i am in also do, but thats maybe just cause we are metalheads and we have no idea of hardcore

Exactly. The "metal community" usually has no idea what they're talking about when it comes to punk.

Hatebreed is metalcore. Or "moshcore". Or whatever. It's just NOT hardcore. Hardcore is not about jocks getting together to beat each other up and hopefully anyone else they can find along the way.

discharge and a bit of black flag

i know that we have no idea about punk - we arent a punk community

but we know what metalcore is, and so we can say that hatebreed isnt (only) hardcore.
