Alongside the institutionally constructed European identity, research shows that insights into citizens’ sense of belonging are valuable as well in assessing questions of identity. The tendency to conflate European identity with EU identity has spurred debates about the components that underlie European identification. The online subsidiarity adopted by the EU through e-platforms has allowed for a new form of citizenship where e-citizens legitimate the issues under debate. This article examines the contents of European and national identities in the e-debaters’ comments (...) posted on the Debating Europe platform. Drawing on narrative and discursive approaches, we propose a framework to operationalize the legitimation and identification categories used by e-debaters within their discursive construction of European identity. The qualitative empirical research shows three main legitimation clusters: the “EU as a loss,” “inclusive gain,” and “exclusive gain.” We discuss these findings within the broader context of Europeanization, identity multiplicity, and the conditions of the EU enlargement policy.
