This study explores the nationalist and exclusionary discourses against asylum seekers in Türkiye through a qualitative analysis of social media reactions to the short dystopian film Silent Invasion. The film, portraying a fictional future where Syrian refugees dominate Türkiye’s sociopolitical landscape, sparked widespread debate and polarized opinions. Using phenomenological methodology, 9989 tweets and retweets posted under the hashtag #sessizistila were thematically analyzed via Maxqda. Findings reveal that nationalist, xenophobic, and populist narratives dominate the discourse, framing asylum seekers as threats to national identity, culture, and security. Discursive strategies reflect a strong “us vs. them” dichotomy, emphasizing fear, victimization, and demographic anxiety. The study identifies four main themes: justifications for or against the presence of asylum seekers, perceived threats to Turkish identity, security concerns, and criticism of political inaction. Posts often reproduce misinformation and stereotypes, portraying refugees as uncivilized, violent, or culturally incompatible. Conversely, a smaller segment emphasizes empathy, human rights, and social cohesion. The chapter underscores how social media operates as both a space for democratic expression and a platform for hate speech, shaping public perception and potentially fueling polarization. The authors recommend that future social cohesion policies actively include the local community, promote media literacy, and address misinformation. This research contributes to the growing body of literature on digital hate, nationalism, and the challenges of integration and coexistence in host societies facing large-scale migration.
