Theodore Roosevelt Quote
It is unwise to depart from the old American tradition and discriminate for or against any man who desires to come here and become a citizen, save on the ground of that man's fitness for citizenship.... We can not afford to consider whether he is Catholic or Protestant, Jew or Gentile; whether he is Englishman or Irishman, Frenchman or German, Japanese, Italian, or Scandinavian, or Magyar. What we should desire to find out is the individual quality of the individual man.
As quoted in The Business of Transatlantic Migration between Europe and the United States, 1900–1914 (2012), by Drew Keeling, p. 161. - Message to Congress (1905)
