The Office for the Security of the German Federal State of Hessen has published a report on anti-Semitism on the German internet, authored by Ann-Christin Wegener. The study focuses on the manifestations and ideological background of anti-Semitic agitation on social networks in Germany.
Wegener wrote that the German authorities usually claim that 90% of anti-Semitic incidents are caused by the extreme right. She suggests that this results from the way the police report anti-Semitic incidents. As long as nothing is known about the motivation or the perpetrators, these incidents are labelled as right wing politically motivated.
Hate crimes committed in the Arabic or Turkish languages lead to less complaints than those in German. One has to also take into account the fact that many anti-Semitic incidents are not reported or do not result in complaints. It is estimated that less than a quarter of Jewish victims of anti-Semitism bring complaints to the police or to the Jewish community.
