The article addresses the ways in which the pandemic may have affected the ways of reactions to social injustices. For the authors, social isolation, the pandemic context and social media interactions favor the spread of negative emotions. Such emotions are activated when a scenario of social injustice is observed, which motivates participation in protests, despite the risks posed by the pandemic. In addition, the authors discuss how separatism has been encouraged in some countries, due to the absence of effective national leadership.
