The democratic potential of literature education has often been accentuated. In this article, we draw on Gert Biesta's subjectification conception of democratic education, and view democracy as a concept open for (re)negotiation in the classroom. We are informed by Chantal Mouffe's agonistic democratic theory, and its view of dissent as a foundational aspect of democracy, in that the struggle itself constitutes the identities of the opponents. Agonistic proposals for democratic education also pay attention to political emotions in the classroom. We pair agonism with Sara Ahmed's view of emotion as performative to explore how power, identity and emotions are entangled in a student group and how this entanglement is integrated in the students' conceptions of democracy. The students were in their last year of upper secondary school in Sweden. We analysed audio recordings from three group interviews with a total of eleven students. The interviews followed a literary discussion about the short story 'Farangs' by Rattawut Lapcharoensap, which was video recorded. The analysis shows that students referred to emotion when constructing the collective identities of themselves and their opponents, and that the power relations between these collective identities influenced what literary interpretations were centred in the discussion.
