“Why are the majority of anti-Semitic acts attributed to ‘right-wing’ German perpetrators? One can see a political motive behind this — growing anti-Semitism can be used politically as a weapon ‘against the right.'” — Tichys Einblick.
… A 2017 survey of German Jews by the University of Bielefeld found that 60% of anti-Semitic attacks were said to have been carried out by Muslims, compared to 19% by far-left extremists and 19% by far-right perpetrators. Muslims were also said to be responsible for 81% of anti-Semitic attacks involving physical violence. The survey found that 70% of German Jews believe that mass migration from the Muslim world has fueled anti-Semitism in Germany.
Nevertheless, German police, possibly under orders from political authorities, systematically assign unsolved anti-Semitic hate crimes to the far right. In one well-known case, police blamed far-right extremists for chanting the Nazi slogan “Sieg Heil” at an Islamist al-Quds rally in Berlin.
