" The ploy of using dark psychology to dehumanise certain ethnic and religious groups is so effective that it has been used repeatedly throughout history. Such racist psychology with discriminatory dehumanisation consists of five basic elements that include alluding to the below par intelligence or morality of the minority group to cause it to be ostracised while boosting the ego of the majority by assuring them of their own superiority; using infestation analogies to make the majority fearful that the minority is a threat to their welfare and security; comparing and referring to the minority as animals with the Nazis having frequently referred to innocent Jewish victims as rats; encouraging the use of violence by the majority who have been brainwashed into accepting that the minority are inhuman; and physically isolating or removing the minority by means of deportation, the formation of ghettos, or the use of concentration camps.
