It is a genuine tragedy, because the Potter books are so rich, and could have been—should have been—truly inspiring pieces of literature. I still think, and will always think, that these books are a dazzling feat of human inventiveness. J.K. Rowling can imagine almost anything. She can imagine fantastic beasts, enchanted castles, oozing potions, explosive spells. But she cannot imagine her way to questioning the deepest injustices of our time, and she cannot imagine why people are offended when she says hurtful and ignorant things about marginalized people.
