EUMC Working Definition on Antisemitism:
Antisemitism is a certain perception of Jews, which may be expressed as hatred toward Jews.
Rhetorical and physical manifestations of Antisemitism are directed toward Jewish or non-Jewish individuals and/or their property, toward Jewish community institutions and religious facilities. In addition, such manifestations could also target the state of Israel, conceived as a Jewish collectively. Antisemitism frequently charges Jews with conspiring to harm humanity, and it is often used to blame Jews for ‘why things go wrong’.
Anti-Semitic acts are criminal when they are so defined by law (for example, denial of the Holocaust or distribution of Antisemitism materials in some countries).
Criminal acts are anti-Semitic when the target of attacks, whether they are people or property – such as buildings, schools, places of worship and cemeteries – are selected because they are, or are perceived to be, Jewish or linked to Jews.
Anti-Semitic discrimination is the denial to Jews of opportunities or services available to others and is illegal in many countries.
