Nazism in popular culture

The term Nazi has become a generic term of abuse in popular culture, as have other Third Reich terms such as Führer (often spelled differently in English-speaking countries). Related terms, such as fascist, Gestapo and Hitler are sometimes used to describe any people or behaviours that are viewed as thuggish, authoritarian, or extremist. Phrases such as grammar Nazi, Feminazi, Open Source Nazi, and parking enforcement Nazi, are sometimes used in the United States. These uses are offensive to some, as indicated by the controversy in the mainstream media over the Seinfeld "Soup Nazi" episode. These types of terms are used frequently enough to inspire Godwin's Law.
Some people strongly associate the blackletter typefaces (e.g. Fraktur or Schwabacher) with Nazi propaganda (although the typeface is much older, and its usage was banned by The Nazi German government in 1941).
In films such as the Indiana Jones series, Nazis are often portrayed as villains, whom the heroes battle without mercy. Video game website IGN declared Nazis to be the most memorable video game villains ever. The main antagonists in the manga/anime Hellsing are vampire Nazis.
