I've encountered this sort of judgemental attitude pretty much my whole adult life because I don't drink.

The drinkers presume that because I choose not to drink, I am therefore being "self-righteous".

I don't drink for various reasons. That's my choice. I also choose not to eat sushi, not to eat calamari, and to use milk only occasionally. My avoidance of the first two of those is a personal taste thing ... I'm not overly fond of seafood. My avoidance of milk is a health issue. It doesn't sit well with me.

Are there things you don't like to eat and drink?
