I think the point is - this book was easy and nearly universal in saying "yeah that is disgusting." So, should Amazon and other retailers now scrutinize their catalogs and start making judgment calls on all books that deal with Pedophilia? Fiction isn't relevent? Why? There is a long history in literature of using fiction to promote ideas and spread ideology.
Anybody ever read this book? It disgusted me beyond all bounds and it includes graphic descriptions of sex between a teen boy and a mid-thirties adult male. I tore my copy into shreds.

Not only was it widely available at all retailers, they made it into a movie. I've never heard of any outcry or push for retailers to remove it from their shelves.
These are not easy lines to draw.
