Another reader on Allen’s novel approach:

I’m going to be holding my nose and voting for Allen, but it will be a pity if he only wins because of Webb’s fiction. Sure, those scenes are sick, but that doesn’t mean they are wrong, either morally or as literature. Flannery O’Conner wrote disturbing stuff, and she did it for God (and was fairly explicit about that motivation, as I understand). More recently, Wolfe’s I am Charlotte Simmons was loved by conservatives, but it certainly has some parts that aren’t exactly Sunday school material. Well, unless said Sunday school actually reads the Bible, which is crammed with perverse stuff. Lot’s daughters, anyone?
Without more context it’s impossible to tell whether those scene’s in Webb’s books are are wrong (a la Lolita, which is a horrible book, regardless of what Derb says) or right (as in the examples above) or somewhere in between.
