In recent decades, politics has become increasingly connected to public opinion and civil society. This process has been particularly amplified with the emergence of social media, platforms in which anyone can express their opinion uncontrollably. There are many issues in which the involvement of civil society is evident: global warming, terrorism and migration are just examples within the plethora of topics in which public opinion has gradually gained an increasingly important position. Issues so delicate and debated that, however, over the years they have been transformed into political instruments for the control or mobilization of the masses by the political class. It is therefore necessary to question what we often call “public opinion”, but which could turn with increasing frequency towards a real “mass opinion”, harmful to the political system and to civil society itself.
