Laura Miller writes: “Conservative book bans recall the old joke about the drunk who loses his car keys in the park but searches for them under a streetlight because that’s where the light is. Conservative parents can’t keep their kids from being exposed to ‘bad’ information or ideas on the internet, but they can badger school boards into withdrawing books containing those ideas. As for the conservative advocacy groups behind the book ban movement, they can’t lose. That’s because their goal isn’t to protect kids but to bring about the (highly profitable) privatization of American education.”
