Neo-Nazism is a post-World War II militant, social, and political movement that seeks to revive and reinstate Nazi ideology. Neo-Nazis employ their ideology to promote hatred and racial supremacy, attack racial and ethnic minorities, and in some cases, create a fascist state. The term "neo-Nazi" describes any post-World War II militant, social, or political movements seeking to revive the ideology of Nazism in whole or in part. Neo-Nazism is a global phenomenon, with organized representation in many countries and international networks. Neo-Nazis regularly display Nazi symbols and express admiration for Adolf Hitler and other Nazi leaders. They have adopted the trappings of Nazism, such as celebrating the birthday of Adolf Hitler, reading his book Mein Kampf, and performing the Nazi salute. The ideology of neo-Nazis is based on the notion of the racial superiority of white people over all other races. They grade races in order of their alleged superiority, with black people and Jews at the bottom of the hierarchy. Homosexuals, Gypsies, and others are also condemned. Although "socialism" is contained in the name of both the Nazi Party and the Australian National Socialist Network, they are not pursuing "socialism" as its normally understood as a left-wing philosophy.
