I'm Straight edge and
i just don't like seeing people drinking all that,
it's a life ruining threat.
Frequently drinking to excess can certainly be destructive. I know a few people who don't drink, or very very rarely do, but it's more a matter of health reasons or personal preference, rather than a particular committment to being Straight Edge. My dad, for one. I don't think I've ever seen him take a drink in his life, but he wouldn't know the term Straight Edge. Of course, he makes up for not drinking by smoking and by drinking more coffee than any single human being should consume.
Personally, I love the vast variety of alcoholic drinks, and although I drink frequently, I very rarely drink with the intention of getting shitfaced. If I had to guess, I'd say that I get drunk less than 1 time out of 10 when I consume alcohol. Above all else, though, I consider myself to be a beer fan.
