Unfortunately, he is pretty much spot on as far as the scene goes...everything Dimmukane listed there is fairly predominant at almost any hardcore show you go to.
Back in September, I went to see Modern Life Is War with Strike Anywhere and Ignite...the vast majority of the crowd was this group of dirty punk kids, all of them with big ass smiles on their faces the whole time that bands were playing. Everyone was there having a good time, and not afriad to show it. It's one of the best shows overall that I've been to.
On the other hand, in August I went to see Converge playing an off-date show with some smaller hardcore and grindcore bands. The whole time, everyone was busy comparing "I'm more hardcore than you" points, and making anyone who didn't fit their image feel that they had no right even being withing line of sight of the venue.
It's happened to other styles of music, and other scenes - hardcore (and especially metalcore) has started to gain popularity among the masses, and it's turned into a fucking fashion show...kind of ironic, since a lot of the bands that are idolized in this genre scream out against that very thing.
Every scene has its fair share of shitheads...we'e covered that already. Khar's estimation is as right as it gets, 95% of "my" scene sucks, but probably so does 95% of his. So does 95% of the indie scene, I could go on and on. On the upside, the scenes themselves have provided Jeph with plenty of mockery potential in past AND future comics here...so I guess we should at least enjoy that...
Okay, end tangent. I'll jump down off my soapbox, let someone else have a turn. Thanks for playing.
