I agree, I need to do my homework on Hitchens. Now I'm curious to do so and it appears I'm wrong that he denied the holocaust so I take that back. (I'll look into this more.)
However, some strongy view him as an anti-semite. Here's an excerpt from an article by writer Benjamin Kerstein:
"Hitchens's bestselling atheist jeremiad, God is Not Great (2007), provides an excellent overview of its author's sentiments on the topic of Jews and Judaism. While the book is ostensibly opposed to all religions equally, Hitchens goes out of his way not merely to criticize Judaism but to portray it in the ugliest possible terms, invoking many of the classic themes of anti-Semitism in order to do so.For Hitchens, the evils he lists are not just religious tenets; they are ingrained in the Jews themselves. The rituals and practices of Judaism, he charges, are debased by the Jews' obsession with money, as exemplified by the "hypocrites and frauds who abound in talmudic Jewish rationalization" and who operate according to the principle: "'Don't do any work on the Sabbath yourself, but pay someone else to do it for you. You obeyed the letter of the law: who's counting?'" (Hitchens's world abounds, apparently, in dutiful shabbos goyim.) Circumcision, he claims, is the "sexual mutilation of small boys" and "most probably a symbolic survival from the animal and human sacrifices which were such a feature of the gore-soaked landscape of the Old Testament." As for anti-Semitism, the Jews brought it on themselves. "By claiming to be 'chosen' in a special exclusive covenant with the Almighty," Hitchens writes, "they invited hatred and suspicion and evinced their own form of racism."
Hitchens's loathing for Judaism, or rather the grotesque caricature he refers to as Judaism, is particularly evident in his treatment of Hanukkah, a holiday marking the 2nd-century B.C.E. victory of a Jewish revolt led by the Maccabees. For Hitchens, the Maccabees' defeat of the Hellenistic regime of Antiochus Epiphanes was a disaster, because Antiochus, far from being a villainous tyrant, had "weaned many people away from the sacrifices, the circumcisions, the belief in a special relationship with God, and the other reactionary manifestations of an ancient and cruel faith."
To put it kindly, this is false; for the rather less benign details, one may consult I Maccabees and Josephus's Antiquities of the Jews. In brief, the "weaning away" lauded by Hitchens involved the forcible suppression of Jewish culture, religion, and ritual, along with torture, imperial occupation, and mass murder, including the slaughter of children: in other words, the very things that this self-proclaimed global humanist violently denounces whenever the Jews are not involved."
