Do you know what day Tuesday is? Take a look at this:
Now, I'm not a big fan of the Emo thing. To be honest, I think it sucks:
"Oh, I'm so depressed even though I live in the suburbs and have a comfortable lifestyle! Woe is me! I'm going to grow my hair like a girl and cut myself to prove I'm hardcore!"
You emo kids want something to be really depressed about? Go live in some dirty overcrowded Third World shithole where you have to step around puddles of piss because they don't have a waste management system.
But still, beating the fuck out of someone because they have a stupid haircut and mope around all the time sounds facist to me. No, I'm not going to beat up any emo kids unless one of them swings on me first...which is an unlikely scenario in the first place because emo kids usually aren't that motivated to expend physical energy.
If you don't like Emo, there's a far more productive way to deal with it than thuggish violence: Simply
show them the ugly truth of what it is they're doing. Make them think, for fuck's sake. After all, a beatdown would just give them one more reason to be emo and give them more "rebel chic". That's just the way they roll.
