Oh, no, no, I have to explain it to other Americans I meet IRL. Make one casual joke about how you wish the US would switch over to Metric because Imperial's a pain in the butt, or about how you don't consider Obama the Antichrist just because you disagree with some of his policies, and get told that "if you don't like the way America is, you can leave". Gee, that seems unproductive. >>
