Leipzig had issued in April 1935. Hoffmann contended that what happened was that on April 9, 1935, the Deputy Mayor of Leipzig, the National Socialist Rudolf Haake, banned all Jewish doctors from participating in public health insurance and advised all municipal employees not to consult Jewish doctors, going beyond the existing antisemitic laws then in place. In response, the Landesverband Mitteldeutschland des Centralvereins deutscher Staatsbürger jüdischen Glaubens e. V (Middle German Regional Association of the Central Association of German Citizens of Jewish Faith) complained to Goerdeler about Haake's actions and asked him to enforce the existing antisemitic laws, which at least allowed some Jewish doctors to practice. On 11 April 1935, Goerdeler ordered the end of Haake's boycott, and provided a list of "non-Aryan" physicians permitted to operate under the existing laws and those who were excluded. Others have contended that, despite the book's "undeniable flaws", it "served to refocus the debate on the question of German national responsibility and guilt", in the context of a re-emergence of a German political right, which may have sought to "relativize" or "normalize" Nazi history. Goldhagen's assertion that almost all Germans "wanted to be genocidal executioners" has been viewed with skepticism by most historians, a skepticism ranging from dismissal as "not valid social science" to a condemnation, in the words of the Israeli historian Yehuda Bauer, as "patent nonsense". Common complaints suggest that Goldhagen's primary hypothesis is either "oversimplified", or represents "a bizarre inversion of the Nazi view of the Jews" turned back upon the Germans. One German commentator suggested that Goldhagen's book "pushes us again and again headfirst into the nasty anti-Semitic mud. This is his revenge." Eberhard Jäckel wrote a very hostile book review in the Die Zeit newspaper in May 1996 that called Hitler's Willing Executioners "simply a bad book". The British historian Sir Ian Kershaw wrote that he fully agreed with Jäckel on the merits of Hitler's Willing Executioners". Kershaw wrote in 2000 that Goldhagen's book would "occupy only a limited place in the unfolding, vast historiography of such a crucially important topic-probably at best as a challenge to historians to qualify or counter his 'broad-brush' generalisations". In 1996, the American historian David Schoenbaum wrote a highly critical book review in the National Review of Hitler's Willing Executioners where he charged Goldhagen with grossly simplifying the question of the degree and virulence of German Antisemitism, and of only selecting
