Late in the previous century I wrote about reverse bowdlerization and an attempt to save The ChildrenTM from the lewdness of The Old Gringo: "No doubt these same people object to the Book of Genesis, because no amount of context can obscure what it was that wicked, wicked Onan was doing to himself."
Pretty much what these folks are doing, actually.
...adding, I've read The Handmaid's Tale (not just the dirty parts!) and Cat's Cradle, the latter in high school or middle school, so all you have to do is read this blog to know the book-banners are right about the slouch toward Gomorrah that these books initiate.
If anyone wants to do a virtual book club, I'll read The House of Spirits and open a thread.
