I think that's what he's trying to explain, that being 'straight edge' has something to do with a pop-culture, as much as being punk has something to do with looking like a punk, being anarchistic AND listening to the music. You can look like a punk and not be one and you can listen to punk without being a punk.
I think all of this is bull**** in the end, but I think this is what he means.
So... Explain the true meaning of Straight Edge to me, as opposed to being drug-free, please
.
And while you're at it, explain to me why you want to have it explained.
