Crises, as critical moments in the process of European integration, are particularly conducive to the increased politicisation of the European Union (EU) and its contestation. The year 2015 saw the peaks of the Greek and the refugee crises, the two crises that put the two flagships of the European project—the Euro and the Schengen zone—into imminent peril, causing a prolonged EU legitimacy crisis. Building on the literature that considers Euroscepticism as a context-dependent and discursive phenomenon, this study analyses Facebook debates that emerged in response to the Greek and refugee crises, trying to identify how the EU was evaluated and how these evaluations were justified. To answer this question, this study involved the qualitative content analysis of over 7000 Facebook comments related to the Greek and migration crises published in 2015 on the pages of the European Parliament and the European Commission. Contrary to the literature that explains popular Euroscepticism by utilitarian or cultural factors, the findings of this study show that the most recurrent justification for negative EU polity evaluations is the lack of democratic credentials. Furthermore, the commentators mostly assessed the EU’s current set-up and, to a much lesser extent, the principle and the future of European integration. Moreover, the Facebook public extensively commented on the level of inclusiveness, particularly bemoaning the lack of inclusiveness of “ordinary” people in EU decision making. Nevertheless, the commentators frequently referred to themselves as “we Europeans” or “we people”, opposing themselves to EU, national, or financial “elites”. Despite its populist elements, this sense of “we-ness” incepted in social media suggests the capacity of transnational online discussion to foster European digital demos.
