Here's another good quote:
"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...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...and we have room for
but one sole loyalty and that is a loyalty to the American people."
Theodore Roosevelt 1907
