Let children read whatever they want and then talk about it with them. If parents and kids can talk together, we won't have as much censorship because we won't have as much fear.
Madeleine L'Engle's 'A Wrinkle in Time' has been targeted by censors for promoting New Ageism, and Mark Twain's 'Adventures of Huckleberry Finn' for promoting racism. Gee, where does that leave the kids?
