Nazi (also the cognates Nazism and Neo-Nazism) is a political epithet invented by Konrad Heiden✡ (7 August 1901 – 18 June 1966) during the 1920s as a means of denigrating the NSDAP and National Socialism.[1] Heiden was a journalist and member of the Social Democratic Party of Germany, whose mother was a Jewess. The term is both an imitation of the nickname given to Marxists of the SDP at the time, Sozi, and a political pun similar to the Austro-Bavarian word for “simpleton”, derived from the fairly common name Ignatz (German language form of Ignatius). It was then popularised abroad by various Judaics and other subversives, including Heiden himself, who fled the country after the NSDAP were elected to government.
The term was regarded as a derogatory epithet by National Socialists and was used almost exclusively by Marxist agitators. Typically the use of Nazi Germany, and Nazi regime, was popularized by Jewish émigrés from Germany after 1933, especially in English-speaking countries. From them, it spread into other languages.
A rare example of its usage by a NSDAP member can be taken from a 1931 work by Joseph Goebbels called The Nazi-Sozi: Questions and Answers for National Socialists. Since the rise of Cultural Marxism the term has been used as a broad Europhobic epithet, eminating from the same quarters, to demonise European people in general and attack leaders who advocate their socio-economic and cultural interests, far beyond the bounds of actual National Socialists. Some have ironically turned the phrase back on its inventors, through the use of “Nazi” as an abbreviation for National Zionism.
Usage
The word itself derives from a slang from German, nationalsozialismus. It coined for its negative sound and connection, as sozi had previously been used to refer to Marxists in Germany, particularly those of the Social Democratic Party of Germany- Sozialdemokratische Partei Deutschlands.
Media manipulators consisting of journalists, Europhobic historians and degenerate entertainment elites routinely use the term creating subliminal reflexive associations within the host population. For examples of popular political correctness and political bias compare the usage of the term “Soviet Union” with “Commie Russia”.
George Lincoln Rockwell reluctantly adopted the use of word in 1959 when he founded the American Nazi Party. He chose to use it for its publicity and shock value.

Needless to say, I don’t give a shit if someone calls me a ‘Nazi’. I’ll accept that term because I know what the person is alluding to, but as for using it myself when referring to other like-minded people – I won’t be doing that. National Socialist is the right term to use!
