The unexpected resounding NO of the Greek referendum of the 5^th July to continued austerity echoed a great disapproval and rejection of a ‘Germany-dominated Europe’ and a strong claim for radical change in Europe while fuelling reactions, which in social networks were discursively and symbolically constructed to express and intensify anti-Brussels and anti-Germany sentiments and to mobilise resistance. The present paper sets out to investigate how discursive constructions and representations of the Self and the Other contributed to bringing closer the NO partisans and to reinforcing a discourse of resistance for political, economic and social change. Relying on comments from Tsipras’ Facebook page, this study lies within Critical Discourse Studies and uses corpus-based methodologies to detect the most frequent words and semantic fields, which seemed to be building a dichotomous discourse between US and THEM while enhancing an in-group cohesiveness around the pre-referendum charismatic personality of Alexis Tsipras.
