"Bullying is a learned behavior. Children are not born cruel. Babies in diapers do not assess each other as too fat, too poor, too dark-skinned, to nerdy, too conceited. Born innocent, they start learning stereotypes as soon as they understand language, and we see bullying behavior in children as young as toddlers. Since preschoolers who display marked aggressiveness have a higher likelihood of being bullies in older grades, the earlier intervention begins, the better the results. It is much easier to inculcate kindness and acceptance into a five-year-old who acts like a bully than a fifteen-year-old who acts like a bully."
