Hatred is a word to describe feelings of prejudice, bigotry or condemnation (see shunning) against a class of people and members of that class. Racism is the most well-known example of this. The term hate crime is used to designate crimes committed out of hatred in this sense.According to evolutionary psychologists, hate is a reaction to people whose interests consistently conflict with one's own. People whose behavior threatens one's own survival interests are to be hated, while people whose behavior enhances one's survival prospects are to be liked or even loved (as in the case of offspring and other genetic kin). The passions of hate arise from several features of our thinking process. These include a desire to strengthen our community and to alleviate our fear. The ability to quickly separate friend from foe is essential to self-defense and safety and provides the origins of hate.
