Should we read a novel whose narrate is racist and anti-Semitic?

Umberto Eco's Italian-language novel The Prague Cemetery (hard to believe but it's the first Eco novel I've read - now about 80 pp. in) is set in about 1895 and is narrated by a young (30 or so?) man, Sabatini (?) who begins by describing his neighborhood, a blind alley on the Left Bank near the Sorbonne, as the most unpleasant and corrupt street in Paris, perhaps in the world - an obvious exaggeration. He's set out to write the story of his life, and he begins by giving an account of all of his biases, prejudices, and hatreds - of just about every race and ethnic group except for his own - and even then, he seems ashamed of his Italian (Piedmontese) background and claims to be more French than Italian. Yet despite his hatred and loathing of everything and everyone, he reserves particular hatred and vitriol for Jews - he's an incorrigible anti-Semite, and he unleashes all of the racial stereotypes that attach to Jews and Judaism. Why would anyone read this novel?! Well, it's obvious that his hatred of Jews comes from his family background and his upbringing by a racist and hateful grandfather, and his attempt to write his life story is an examination of the origins of racism and anti-Semitism (we learn early on that he may be a victim of multiple personality disorder and may at times exhibit the personality of a Jesuit priest). We also can sense of course a distance between his views and Eco's (Eco of course plays with the idea of narrative frames, stories within stories, etc. - very much in vogue in the late 20th century, especially in Europe, when he wrote this work). But is that enough? It's one thing to examine the roots of racial hatred and another to exploit racism. Just about any reader, but any Jewish reader in particular, will be put off by Eco's wallowing in the stereotypes of the past, largely because those stereotypes have not vanished and in fact are nourished and kept alive by works such as this. Yes, this novel, like all of Eco's works apparently, is narrated at a quick pace, presents (male) characters w/ strong personalities, and is full of esoteric and recondite information about a vast range of Euro-centric subjects - history, philosophy, the arts, languages, theology. It's enough to keep me interested and to keep me reading for at least another day, but if the novel continues to wallow in the lower depths of racism I won't give it any more credence or attention.
