Dehumanization
Dehumanization can be used against a racial group or ethnicity, by comparing them to animals or monsters. In this way it is easier to abuse people of another group. For example, black people have been dehumanized by racist images comparing them to apes. Researchers say that this dehumanization continues to exist today: it can affect the punishment for a crime. Some people, such as Ota Benga, an African Mbuti man, were held in human zoos. They were shown for visitors' amusement, just like zoo animals.
