economic antisemitism, religious antisemitism, and political antisemitism as examples. König points out that these different forms demonstrate that the "origins of anti-Semitic prejudices are rooted in different historical periods." König asserts that differences in the chronology of different antisemitic prejudices and the irregular distribution of such prejudices over different segments of the population create "serious difficulties in the definition of the different kinds of anti-Semitism." These difficulties may contribute to the existence of different taxonomies that have been developed to categorize the forms of antisemitism. The forms identified are substantially the same; it is primarily the number of forms and their definitions that differ. Bernard Lazare identifies three forms of antisemitism: Christian antisemitism, economic antisemitism, and ethnologic antisemitism. William Brustein names four categories: religious, racial, economic, and political. The Roman Catholic historian Edward Flannery distinguished four varieties of antisemitism: political and economic antisemitism, giving as examples Cicero and Charles Lindbergh; theological or religious antisemitism, sometimes known as anti-Judaism; nationalistic antisemitism, citing Voltaire and other Enlightenment thinkers, who attacked Jews for supposedly having certain characteristics, such as greed and arrogance, and for observing customs such as kashrut and Shabbat; and racial antisemitism, with its extreme form resulting in the Holocaust by the Nazis. Louis Harap separates "economic antisemitism" and merges "political" and "nationalistic" antisemitism into "ideological antisemitism". Harap also adds a category of "social antisemitism". religious (Jew as Christ-killer), economic (Jew as banker, usurer, money-obsessed), social (Jew as social inferior, "pushy", vulgar, therefore excluded from personal contact), racist (Jews as an inferior "race"), ideological (Jews regarded as subversive or revolutionary), cultural (Jews regarded as undermining the moral and structural fiber of civilization). Cultural antisemitism Louis Harap defines cultural antisemitism as "that species of anti-Semitism that charges the Jews with corrupting a given culture and attempting to supplant or succeeding in supplanting the preferred culture with a uniform, crude, "Jewish" culture." Similarly, Eric Kandel characterizes cultural antisemitism as being based on the idea of "Jewishness" as a "religious or cultural tradition that is acquired through learning, through distinctive traditions and education." According to Kandel, this form of antisemitism views Jews as possessing "unattractive psychological and social characteristics that are acquired through acculturation." Niewyk and Nicosia characterize cultural antisemitism as focusing on and condemning "the Jews' aloofness from the societies in which they live." An important feature of cultural antisemitism is that it considers the negative attributes of Judaism to be redeemable by
