“It is idle to say you are only fining a man a farthing, if he chooses to say it is his lucky farthing. It is waste of breath to call a thing a rag when he calls it a flag. This is the fallacy of those who, like Mr. Gerald Stanley Lee, the able American critic, imagine that a war must be a misunderstanding, which social intercourse and explanation would have set right.”

1910s, Address to the Knights of Columbus (1915)
Context: 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. The men who do not become Americans and nothing else are hyphenated Americans; and there ought to be no room for them in this country. The man who calls himself an American citizen and who yet shows by his actions that he is primarily the citizen of a foreign land, plays a thoroughly mischievous part in the life of our body politic. He has no place here; and the sooner he returns to the land to which he feels his real heart allegiance, the better it will be for every good American. 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.

1910s, Letter to the American Defense Society (1919)
Context: In the first place we should insist that if the immigrant who comes here in good faith becomes an American and assimilates himself to us, he shall be treated on an exact equality with everyone else, for it is an outrage to discriminate against any such man because of creed, or birthplace, 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 flag, the American flag, and this excludes the red flag, which symbolizes all wars against liberty and civilization, just as much as it excludes any foreign flag of a nation to which we are hostile. 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.
