“This research deals with a parcel of the protests that have been taking place over the last few years, particularly since 2010: those protests in which the protesters, instead of rebelling against the legitimacy of the system, have preferred to accept the regime’s remaining in place and consequently have manifested their discontent via playing by the constitutional rules of the game.

The first argumentative line rests on the sociology of social movements and from there proposes some conceptual definitions as to what playing by the rules means to social protests.
