Jesus fuck... you're doing it so wrong, kids. You're going to realise how much you looked like asshats some day soon.
Being metal has little to do with your appearance, and a whole lot to do with your enthusiasm towards ear-bleedingly sick blast beats and guitar that'll melt your face right off.
Got a job, have to cut your hair and wear a suit? Can't wear combat boots in the office? Still a diehard fan of metal-as-fuck bands? Fight on soldier, you're in the metal army.
Labelling people and the idea of "belonging" to different scenes is just fucked, and people need to wake up to themselves. It's just music, not everyone is going to like what you like, and you're sure as shit not going to like everything that they like. It's not the end of the world.
This woman knows the score. I'd back her up any day of the week!
There's one thing that you should take away from this post: the knowledge that despite what you may think....
Old ladies are metal as fuck.
