I can understand people who don't drink, but I don't understand people who have never drank. It feels like an obvious personal flaw, a sign of cowardice, that you would not have even tried something so routine and common in our society. If you have tried alcohol, and decided it wasn't for you, then that it all the more courageous. But it feels like you just aren't exploring all that life holds. Or, you don't have faith in yourself that you could get away from it.

There's also this societal concept that everyone has vices. And people would rather be able to recognize and see your vice, rather than have it be unknown. Bill Cosby comes to mind.
