When did they take down the sign?

When did they take down the sign? You know, the one that said, "Give me your tired, your poor, your huddled masses." When did they take it down? Because for years folks came. They came by the boat load. To find freedom. And their children were born free. Americans. And now, when a new, darker people, a people speaking a new language have come to find that same freedom, suddenly folks who's parents came to find freedom themselves want to turn off the lamp and close the door. But when did they take down the sign?
