 Detractors have contended that the book is "profoundly flawed" or "bad history".Some historians have criticized or simply dismissed the text, citing among other deficiencies Goldhagen's "neglect of decades of research in favour of his own preconceptions", which he proceeds to articulate in an "intemperate, emotional, and accusatory tone".In 1997 the German historian Hans Mommsen gave an interview in which he said that Goldhagen had a poor understanding of the diversities of German antisemitism, that he construed "a unilinear continuity of German anti-semitism from the medieval period onwards" with Hitler as its end result, whereas, said Mommsen, it is obvious that Hitler's antisemitic propaganda had no significant impact on the election campaigns between September 1930 and November 1932 and on his coming to power, a crucial phenomenon ignored by Goldhagen.
