 German protections for freedom of ideas and expression are superseded by various provisions against "anti-constitutional" ("verfassungsfeindlich") politics.In practice the ban on "anti-constitutional" politics targets two main categories, Nazism (including Neo-Nazism) and Communism.In the "Annual Report on the Protection of the Constitution" these categories are discussed in the main chapters on right-wing extremism and left-wing extremism, respectively.
