This chapter synthesizes the main findings of the book, advancing the concept of alternative otherness to explain the transformation of political discourse on immigration in platformized environments. The analysis shows that immigration is no longer primarily constructed through a direct opposition between a national “us” and a migrant “them”, but is increasingly mobilized as a discursive resource within broader dynamics of political antagonism. Across the empirical case studies, the focus of othering shifts towards political opponents, institutions, and symbolic adversaries, while migrants are progressively marginalized as narrative subjects. The chapter identifies key cross-cutting patterns, including the centrality of conflict and delegitimization, the convergence between populist communication and platform logics, and the increasing role of multimodal and AI-generated content in shaping political discourse. It further highlights how these dynamics reinforce processes of polarization, normalize incivility, and contribute to the erosion of voice and representation for migrants. The chapter concludes by outlining the theoretical, methodological, and empirical implications of these transformations for Critical Discourse Studies and future research.
