They forgot to mention that finding Jesus is part of it. And taking it up the arse.
Only kids I have ever seen that behave like the first-mentioned "straight edge" are the hard-core Christians up the road. But these kids, some of them actually seem like normal hardcore kids...
These other kids that are fighting and shit (the gang kids mentioned afterwards), the violence shit going, it's partly normal.
It seems it's primarily just kids who have that teenage urge to "belong". And it also is showing a cross-view of normal culture. The violent shit kids, the good kids who let people go and do what they want.
Either way, anyone with half a brain shouldn't encourage drugs, however good they are, so it's a good thing going. And the kids who are violent, hopefully they just kill each other out.
Ps thanks for posting this, it was a good waste of an hour.
