I am very familiar with the straight edge scene. It has alot to do with the hardcore punk scene. Bands like Minor Threat, Youth Of Today, Four Walls Falling, etc...however, I'm as "crooked edge" as anyone can come so I won't comment anymore on it.
Personally, I have nothing against it but I believe in living your life to it's fullest...even if it means that you die young. Your only going to go around this merry-go-round once in life so make the best of it. Fuck giving up the pleasures in life.
