This paper aims at providing a new systemic contribution to research about perceptions of antisemitism/Judeophobia by contemporary Jews in 12 European Union countries. The perspective – the viewpoint of the offended side – has been less prominent relatively in research literature on antisemitism. The data analysis demonstrates the potential power of Similarity Structure Analysis (SSA) as a better theoretical and empirical tool to describe and conceptualize the contents of chosen research issues. After a brief review of some methodological problems in the study of antisemitism, this paper will re-elaborate data first published in the report of the 2018 FRA study Experiences and Perceptions of Antisemitism – Second survey on Discrimination and Hate Crimes against Jews in the EU (FRA 2018a). Topics include the perceived importance of antisemitism as a societal issue, the contents of anti-Jewish prejudice and discrimination, channels of transmission, perpetrators of offenses, regional differences within Europe, and the role of antisemitism perceptions as a component of Jewish identification. Special attention is paid to the distinction between cognitive and experiential perceptions of antisemitism, and to the typology of practical, populist, political, and narrative antisemitism.
