 Uncivil disobedience is not a distinct category of political action, but a cluster concept or umbrella term that can be used to designate acts of principled disobedience that may or may not be communicative, and which violate one or more of the marks of civility by being covert, violent, evasive, or offensive (Delmas 2018a, 2020; Lai 2019). Examples include animal rescue, Sanctuary assistance, sabotage, ecotage (e.g., monkeywrenching and tree-spiking), graffiti, leaks, government whistleblowing, hacktivism (including DDoS attacks), guerrilla protests, and riots. These various act-types do not share any essential property, besides violating one or more of the commonly accepted criteria of civility. Each form of uncivil disobedience must be examined (conceptualized and assessed) on its own. By conceptualizing uncivil disobedience, scholars intend to counter the theoretical impetus to make the concept of civil disobedience ever broader to encompass protests that one approves of, but which do not fit the standard account and may not even fit activists’ self-understanding either. For instance, in her 1913 speech “Freedom or Death”, the suffragist Emmeline Pankhurst described herself as a “soldier” in a “civil war” waged against the state and defended the use of militant tactics, including heckling, window-smashing, sabotage, arson, and hunger strikes: radical defiance was the point of such uncivil tactics. Identifying some principled disobedient acts as uncivil makes room to focus on their justification. Scholars have defended such uncivil disobedience as political rioting (Pasternak 2019), vandalism (Lim 2020; Lai 2020), violent protest (Kling and Mitchell 2019), coercive strike tactics (Gourevitch 2018), and direct action (Smith 2018).
