@oralloy,
Neo-Nazism stands for the resumption and spread of National Socialist ideas and the continuation of the NSDAP party programme after the Second World War and the end of the Nazi dictatorship.
Representatives of neo-Nazism are called "neo-Nazis" - the term stands in contrast to "Altnazis" (
old Nazis, persons who were already supporters of National Socialism during the Nazi era, held leading positions in the Nazi state and continued their careers after 1945 without any recognisable renunciation of the Nazi past).
