In fact, parents can help pave the way for bullying behavior in kids when they don’t teach their children to respect differences in people. Some parents may pay lip service to the idea that all people are equal, but if their actions reveal a different attitude, their kids will pick up on it. If parents talk disparagingly about other groups of people or tell racist, sexist, or homophobic jokes, the message they’re sending is: “All people are not alike, and some are better than others.”
“Kids pick up on those things,” says Williams. “They learn that people have more or less value.” So be aware of what you say at home — and how it can translate into aggression in your child at school.
