Liberal democracies have been hit by political populism and, thanks to the almost unlimited penetration of the Internet, narratives that would be stopped by editorial mechanisms in a serious media environment have informational reach. Social networks and so-called alternative media provide recipients with one-sided content and a narrow view of social issues. The plurality of competent opinions, which is the basis of a democratic society, is disappearing from the debate, and part of the population has slipped into having a black and white vision of the world. After the global Covid-19 pandemic, the most discussed topics are the Russian invasion of Ukraine and the energy crisis. Governments and the European Union are looking for ways to respond to the hybrid information operations by which authoritarian regimes have long sought to subvert democratic environments from within. Society is polarising. The aim of this study is to use a theoretical background to analyse Slovak politicians on social networks, where they have virtually unlimited space to spread lies, distorted facts and anti-system views.
