What the legal drinking age and what I think about this issue are 2 different things. The fact that we as a society put so much effort into keeping those under our ridiculous drinking age only works to glorify drinking in the eyes of kids. They spend years dreaming of the magic that is alcohol.
In my mind 18 means you're an adult and welcome to make your own choices. If one of those choices is the stupid one to let frat boys talk you into drinking yourself to death, well, it just is.
