1. 1. Countering Terrorist Content Online: Removal = Success? : A Critical Discourse Analysis of the EU Regulation 2021/784

   Kandidat-uppsats, Försvarshögskolan

   Författare :Nina McCarthy Hartman; [2024]
   Nyckelord :Critical Discourse Analysis; Content Moderation; Counter-Terrorism; EU;

   Sammanfattning : This thesis critically interrogates the underlying assumptions which legitimise the hard regulation of online platforms regarding terrorist content, by turning to the case of the EU Regulation 2021/784. Utilising qualitative critical discourse analysis, the study analyses how the EU's strategy against terrorist content online is discursively legitimised through the lens of Theo van Leeuwen's framework for discursive legitimisation strategies, focusing on moral and rational justifications.
