We don't ridicule a first grader for failing a math problem - we teach them. Yet in public discourse, cultural conflict, and political debate, we often treat adults who "get it wrong" not as students, but as enemies. Why We Don't Mock First Graders (And Shouldn't Expel Adults Either) confronts this contradiction at the heart of modern intolerance. Spanning racial bias and religious difference to online outrage and political polarization, this is not a demand to agree with everyone. It's a call to stop giving up on people. Because just as we give children the chance to learn what they haven't yet been taught, adults - in all our stubbornness, missteps, and untapped potential - deserve the same grace. At its heart, this book is about the long, unfinished lesson of being humans. How can we challenge without condemning? How do we teach without shaming? And how can we disagree without erasing one another?
