This is helpful. The German Left Party - Die LINKE - has often been accused of anti-Semitism, but Diether Dehm - aka "IM Willy" (IM - "Informeller Mitarbeiter" - Stasi informant) explains that "anti-Semitism" is "mass murder" ("Antisemitismus ist Massenmord"). Since no one is advocating (anymore) the mass murder of Jews, anti-Semitism de facto does not exist.
Diether Dehm is one of the more vocal leaders of the Querfront (cross-over front) - the union between far-left activists and right-wing extremists - who rail against the United States and Israel, while agitating for close ties with Vladimir Putin.
Dehm recently hired the former-Red Army Faction (RAF) terrorist Christian Klar as an assistant. Klar was recently released (!) from prison where he was serving a life sentence for the murders of Juergen Ponto, Hans Martin Schleyer, Siegfried Burback and others during RAF operations in the 1970s.
