wiki: A possible reason why some German Jews supported Hitler may have been that they thought that his antisemitism only was for the purpose of "stirring up the masses".[1]
The seemingly ironic fact that a Jewish association advocated loyalty to the Nazi programme gave rise to a contemporary joke about Naumann and his followers ending their meeting by giving the Nazi salute and shouting "Down With Us!".[7][8]
Despite their extreme patriotism, the German government did not accept their goal of assimilation. The Association of German National Jews was declared illegal and dissolved on 18 November 1935.
