Theodore Roosevelt On Immigration

Though often derided by conservatives as a progressive, Teddy Roosevelt was a passionate defender of America and Western civilization. Consider these quotes from TR on immigration:
“We should insist that if the immigrant who comes here does so in good faith, become an American, and assimilates himself to us. He should then be treated on an exact equality with every one else, for it is an outrage to discriminate against any such man because of creed or birth-place or origin. But this is predicated upon the man’s becoming in very fact an American and nothing but an American. If he tries to keep segregated with men of his own origin and separated from the rest of America, then he isn’t doing his part as an American. There can be no divided allegiance here. Any man who says he is an American, but something else also, isn’t an American at all. We have room for but one language here, and that is the English language, for we intend to see that the crucible turns our people out as Americans of American nationality, and not as dwellers in a polyglot boarding-house; and we have room for but one soul loyalty, and that is loyalty to the American people.” – Theodore Roosevelt, Private Letter, January 3, 1919
“There is no room in this country for hyphenated Americanism. When I refer to hyphenated Americans, I do not refer to naturalized Americans. Some of the very best Americans I have ever known were naturalized Americans, Americans born abroad. But a hyphenated American is not an American at all … The one absolutely certain way of bringing this nation to ruin, of preventing all possibility of its continuing to be a nation at all, would be to permit it to become a tangle of squabbling nationalities, an intricate knot of German-Americans, Irish-Americans, English-Americans, French-Americans, Scandinavian-Americans or Italian-Americans, each preserving its separate nationality, each at heart feeling more sympathy with Europeans of that nationality, than with the other citizens of the American Republic … There is no such thing as a hyphenated American who is a good American. The only man who is a good American is the man who is an American and nothing else.” – Theodore Roosevelt, Columbus Day Speech, October 12, 1915
