Query: Hating a band because they aren't "true" punk rock is one of the most ignorant things I've ever heard.

If you don't like Green Day, that's fine. Everyone's entitled to their own opinion. But if you hate a band because they aren't punk, you're an idiot. Some of you just need to accept the fact that some of us are going to like Green Day. Have any of you even listened to a Green Day song? I bet you haven't. It's not fair to call all of us fans preppy girls who go by whatever MTV tells us to do while we wear heavy eyeliner and slit our wrists in our rooms and cry because our parents won't take us to the mall. That sort of thing applies only if you do watch MTV. I've never watched MTV, and I don't plan to anytime soon. I own all of Green Day's albums and am proud to say I enjoy them all.I like Green Day, and I'm not ashamed to admit it. But if I'm a poser/prep because I like a certain band, then I guess I'm a prep.
