A couple of years ago I saw part of a documentary on PBS called Chasing Churchill, in which Churchill’s grandaughter retraced key moments in his life. In the documentary, his grandaughter states that Churchill was “half-American on his mother’s side.” As soon as I heard that I thought, “That’s impossible. American isn’t an ethnicity. You can’t be half American or a quarter American. If you’re an American citizen, you’re American! If not, you’re not American.” I asked my brother, and he agreed.
Are we alone on this? Can American be considered an ethnicity like Italian or German or Chinese? Can a person be half American?
