Digital spaces and political antagonism: Towards a new ecosystem of dissent?

This study investigates the role of digital political communication in the processes of public discourse radicalization and social polarization. Through a critical review of the literature and the analysis of recent events coordinated through online platforms, the research highlights how the circulation of emotional and antagonistic language contributes to reinforcing disinformation, eroding trust in institutions and reshaping the forms of political participation. While digital media expand opportunities for expression and collective organization, they also foster the emergence of “self-confirming” environments that intensify symbolic and ideological conflict. The study underscores the need to develop policies and counter-narrative strategies, as well as regulatory frameworks capable of preserving the quality of democratic debate within the digital ecosystem.
