I was raised Southern Baptist. Neither of my parents has ever had a drink which makes sense, because both of their fathers were alcoholics, which made for poverty stricken and miserable childhoods for them. I, however, am happier as a Presbyterian...I really don't think the Bible says you CAN'T drink.
Anyway, I drink very very little. In college, we were really living on the wild side when four of us shared one bottle of wine on a Saturday night. I hate beer and most mixed drinks. I admit, however, that after being down here in Texas for 23 years, a margerita on the rocks with salt really hits the spot on a hot day. And I also admit that I have gotten through quite a few work related cocktail parties with the help of a glass of wine.
When I was growing up (60s and 70s) my parents were very defensive about not drinking and felt alienated ay many social events. Now LOTS of people don't drink for many reasons, which is a lot nicer for everyone.
