the Nazis.... The casual expressions used by both men in speaking of the Jews were such as to make one cringe, because one would not speak so of even a most degenerate people. "When I indicated my disbelief in their racial theories, they said what other Nazis had said: 'But surely you, a perfect type of Aryan, could not be unsympathetic to our views'.... I had the impression that they really do set unbelievable store by such physical characteristics as long heads and light hair." So convinced was he that the Jews were marked for destruction in Germany that he appealed to the international community to help settle them outside the Reich - but had very little success. As Deborah Lipstadt wrote in her review of the diaries, now published as a book, Advocate for the Doomed, "McDonald, unlike many of his contemporaries, tried to make a difference in what would become a unique story of doom and destruction."
