Their whole attitude is so pretentious. Just because they play hardcore does not make them instantly better than any other band. They aren't even original, they are carbon copies of bands that have broken up. They act like because they play shows in kids basements and sweat that makes them a 'real band" unlike some band that play the house of blues.
Basically their attitude sucks and it's disheartening to see musicians tear down other bands just because they don't play house shows, or "hardcore" music.
I'll type out more thoughts in the morning if you'd like, with examples from other interviews and such.
