How has anti-Semitic filth evaded amazon.com's filters?

Read through the reviews of Bernard Malamud's Pulitzer Prize winning "The Fixer" at www.amazon.com, and you'll see a lead to a sickening review title, "A brief and painful history of why Christians were annoyed by Jews and what they did about it," February 24, 2008
HOW DISGUSTING AND SHAMEFUL!!! You want to know about Christians' treatment of Jews? Begins with medieval era expulsions from towns or nations, and it caps with genocide, The Holocaust, in World War II.
Doesn't anyone vet the reviews?!?! How did this post last in the system for a year and a half??
Report this to amazon.com By the way, I'm of Christian background.
