I can understand why this book was complained about at first, but I have a hard time wrapping my brain around the book being banned today. It's already made an indelible mark on the literary landscape, so banning it... what's the point? You can maybe manage to shield your three-year-old from gay penguins for a while, or protect your twelve-year-old from anything by Chris Crutcher, but... it's Catcher in the Rye, dude. You already lost the battle. Why fight it?
(I said some would be less complicated than others.)
