There is something unsettling about immigrants because … well, because they chatter incomprehensibly, and they get in everyone's way. Immigrants seem to be bent on undoing America. Just when Americans think we know who we are—we are Protestants, descended from Western Europe, are we not? —then new immigrants appear. We—we who are already here—we don't know exactly what the latest comers will mean to our community. How will they fit in with us? Thus we—we who were here first—we begin to question our own identity.
