And hate comes from dehumanizing others. If someone views another person as less than human, harming or killing that person will be just like killing any other animal. Hateful beliefs such as racism, anti-Semitism, and misogyny dehumanize entire groups. When people respect and work to understand each other, violence decreases. Hate can also come from being disconnected from others, marginalized, misunderstood and ignored.
Disconnected people are more likely to dehumanize others and behave violently.
Don't laugh at jokes that use hateful ideas and certainly don't repeat them. Don't be afraid to call someone on a hateful or degrading comment about another group. Hateful beliefs are like a cancer. They can spread, invade, and destroy. Stop them before they spread.
