You'll find alot of metalheads listen to various genre's and not just 'metal'.
Now, metalcore... I'm not too keen on the music, nor the image, but that's just my opinion.
1) Ear-raping screams.
2)
Their image. Especially fringes.
Suicide Silence:
The lead singer looks like an Oli Sykes clone, who himself is a terrible singer and looks like a pre-pubescent child along with the rest of the band.
Having a fringe is incredibly infuriating, speaking from personal experience.
Why have a fringe when you could have a kick-ass beard and long hair?
...
and an axe.
3)
The fans.
Generally popular amongst teenage boys and girls, which in turn annoy me, ESPECIALLY emo boys (again, speaking from past experience).
Why you would want to wear skinny jeans is beyond me. I don't see the appeal in constricting, tight clothing that makes getting a boner in a public place a
very awkward situation.
This is a just a quick rant, and not a direct attack on you. Apologies if you're really into metalcore. I'm not saying "this is what you should think!"
because you're not me.
I don't openly put people down in public, nor on forums about their tastes in music as I tend to think of myself having quite a diverse music taste, varying from Ambient to Death Metal with a few exceptions. Music taste is a touchy subject, and people take other people voicing their opinions to heart too easily, because it's something close to them, something they can relate to. Perhaps it has comforted them in a time of need, or they've got a crush on the singer.
