Most edge kids I've met don't really give a fuck about people who drink. I'm starting to think that these militant edgers might be an urban legend? Or at least the extent of their prevalence.
Not an urban legend, but they were a lot more prevalent about 10 years ago, and evidently even bigger another 10 years before that. They've slowly faded away over the years as those guys break edge and/or stop going to shows. Certainly minimal these days, although it's not unheard of in the Boston scene.
