Theodore  Roosevelt on Immigrants and being an AMERICAN in 1919. 

                "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 person's becoming in every facet 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... 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     Jan 1919
