Book excerpt: In recent years, hate incidents, whether based on race, gender, sexual orientation, nation of origin, or any other perceived difference, have become increasingly common in schools. Students who aren't the victims of hate and intolerance are almost certain to witness it. This unstinting but ultimately optimistic book defines hate and intolerance, explores the reasons some people express hate toward others, and gives readers a blueprint for recognizing and deflecting hate with nonviolence and kindness. Ten questions for an expert, myths and facts about intolerance, and thought-provoking sidebars round out this timely volume.
