Wow, is this thread really all about The Bluest Eye? It’s not an amazing book, but it isn’t half so bad as all that! High school students aren’t just little sponges, she should be reading books she disagrees with, so that she can learn to critique them intellegently, not simple react to them as so many students do now. And the book is focused on the victim and her suffering; it does use the rapist point-of-view at times, which is actually very helpful to the reader (much like a poor imitation of Lolita, which is entirely from the point-of-view of the rapist and entirely focused on the suffering of the victim).
The main thing is that modern literature likes to look at the underside of the world, if your daughter is going to get through any University English program she needs to be able to read and understand this literature. Even in good Catholic universities (I went to Steubenville) she will be reading the likes of Toni Morrison, Nabakov, Faulkner, and others who like darker themes. Toni Morrison is one of the least talented, but you can’t ban her for that.
If it really disturbs you, read it, and discuss the book with her outside of class, ask how it is being discussed and let your daughter tell you what she thinks of the book. You might be pleasently surprised.
God bless,
