Trivium's singer is a nice person. I don't think any band deserves to be spit on or boo'ed. It doesn't get you anywhere, it lessens the respect for the crowd as a whole from the other bands' points of view, and it's just fucking stupid. They're not gonna leave the stage because of your chanting. How would you feel if you were playing a major show and the whole crowd started chanting like that. Yes, I know, you're gonna say you would deserve it if you sucked that bad... but.. Trivium has REAL fans, a ton of people actually love the band, it just wasn't completely the right crowd for them. Show some respect regardless of whether you like the music or not.
