Here's an Afghan proverb that I like: "Some people use a glass for water, some for milk, and others use it for wine -- so should we break all the glasses, or only punish the one who drank wine in it?" The problem is that it doesn't work so well in a culture that doesn't consider drinking alcohol a sin.

The expression was quoted as a defense of cable TV, which has been banned by the Afghan Supreme Court because Indian programs featuring scantily-clad women.
