I don't mean to derail the thread, but would you mind adding how people react when you don't drink? When I first started college, I had read Sipping Saints, and was told by some friends that all drinking was wrong. (They drank grape juice for Communion.) I went to a Lutheran School, and on my first day, my RA was giving us an orientation, asking us about ourselves, and then asked if we drank (which I don't think I could legally at that point anyway.) I said no, and he said, "no? Not at all? Never???" I found it kind of annoying, since 75% of Americans identify as Christian, but drinking, and drinking heavily, was readily accepted (despite the damage it can cause, what the bible says about drinking, drunk driving, etc.), while abstaining is not.
I respect people who don't drink at all, especially since from a societal position it is a difficult stand to take, and don't ask all the "why???"'s because I don't think that it is something that one should need to justify.
