This article explores the issue of ethnic attributions versus options pertaining to Jewishness in Germany. The methodology is a combination of standard ethnographic fieldwork with Berlin-based high-school students before, during and after visits to the Jewish Museum Berlin (JMB) and auto-ethnography detailing and analysing my own experiences in and outside of the research sites. My goal is to illustrate particularities of interactions in sites like the JMB by contrasting the way in which Jewishness is handled in and outside of the standardised research situation. Further, the material points to continuities between anti-Semitism and Islamophobia. My analysis aims to open up further, productive discussion on this point.
