"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
