Well, I'm never against any form of music. Be it Punk, Metalcore, Emocore, Hardcore. I think it's never about the music genre. You might not like Bullet For My Valentine but some other kid out there depends on it to get through the day just like how you do with all your other stuff, perhaps heavy deathmetal stuff or whatever.
I only dislike the notion of music becoming a trend. Such as in the emo music group. It's almost as though they feel as if they dont wear eyeliner, skinny jeans, tight tees or have piercings, they don't belong.
Screw that man guys. Music was always emo. Just not in that new conceptual sense of the word.
