I've never drank and don't plan to. I just tell people I'm allergic to X in the alcohol. It's easier than trying to make up a reason for why I don't drink and people don't think I'm weird.
While I do drink, I sympathize with you; there's a very unfair notion that abstaining is only the result of ignorance or backwards moral hangups, and given the derisive term teetotaling. Your decision is firmly your own.
