Core is the reference to Hardcore. Metalcore is the bend of thrash and black metal with Hardcore punk, you see this mostly in bands like Zao, Poison The Well, and Shia Hulud. So YES, Metalcore is metal. Deathcore is this mix of Death Metal with Metalcore but really I hear no difference aside from the fact that in Deathcore they tune to drop B and the screamer does mostly lows. and NO its not rock. And before you say its commercialized metal think about this, what gets more air play?
Deathcore/Metalcore are fake commercial representations of metal, of course we don't consider those metal.
It really depends on the band, I'll consider it metal if it has more elements of metal (I.e Veil of Maya, Unearth, The Human Abstract, Born of osiris) But it has more elements of hardcore, then I'll lump in that part (I.e. a day to remember, the acacia strain, bring me the horizon)
Yes, at least some of them. If the band has more of a metal sound than a hardcore (core) sound, then of course. Metalcore and Deathcore are not just watered down forms of metal. There are many good bands in those genres.
I don't consider it a genre of metal but it definitely has metal influence (obviously, hence the name). I would consider it a genre of hardcore because it's more hardcore than metal. Usually if it's more metal than hardcore, it is by default, thrash metal. There's a few bands that stray into the gray areas (for example Between the Buried and Me) but that's hardly ever the case. Metal itself is it's own separate genre from rock but both Traditional Heavy Metal and less death sounding Thrash Metal (Such as Metallica, Anthrax, Testament and NOT Slayer, Kreator, etc.) are subgenres of rock that bridge the gap between metal and rock. Most metal outside of those genres incorporate quite a bit of classical, jazz, world and many other different styles of music into one of the most diverse genres ever to be created. It's fundamentally different from rock. And no, metalcore and deathcore are definitely not rock.
