Professor McBroom argues that the events of the Holocaust do not require special, unique or extreme explanations. Rather the behavior of victims, perpetrators, and bystanders can be understood and explained by established principles of social science. As such, events like those of the Holocaust are natural phenomena and have not only occurred in instances other than the “final solution,’ but can happen any time that certain relatively few conditions are present. McBroom cites sociological studies, historical precedents and intercultural research to show how “eliminationist ideologies”- such as that of the Nazis- are developed and prosecuted.
