The truth is, being an American is hard. Being part of a democratic government is hard. Being a citizen is hard. It is a challenge. It's supposed to be. There's no respite from our ideals. All of us are called to live up to our expectations for ourselves -- not just when it's convenient, but when it's inconvenient. When it's tough. When we're afraid. The tension throughout our history between welcoming or rejecting the stranger, it's about more than just immigration. It's about the meaning of America, what kind of country do we want to be. It's about the capacity of each generation to honor the creed as old as our founding: "E Pluribus Unum” -- that out of many, we are one.
