I just finished rereading Bovary, and although the two novels are quite different in their technical astuteness Etienne, I have to say, I can see why Flaubert was put on trial, and why Nabokov ended up with more notoriety than homage. Madame Bovary and Lolita are entirely cynical and nihilistic. Damning and unforgiving visions, not just satires, and this is why regular people rebel against either text. It is not the sex; it is the reduction of the human animal to the lowest common denominator. Name me one redeeming aspect in either story. Give it a shot. These men had no true sympathy; it is ontological buffoonery they both relish, their own wit and wry irony.
Censorship is the worse evil, but that doesn't mean affront against the text isn't a natural response.
