In a world filled with “ambient violence”, public protest is a vital signal of shared discontent. The essential compulsion at the heart of protest, however, is conventionally not recognised for what it is: solidarity with those suffering injustices. Amid authorities’ often-fierce efforts to curtail gatherings of people whose experiences of injustice propel them into the streets, a sharp rise in public protests has been perceived since the early 2000s. Thousands of column inches dedicated to reporting on protests are rivalled in (...) volume only by the reams of academic theories produced around causes. Despite this overabundance of discourses, it often remains unclear what protest, at heart, constitutes. That is, what are we talking about when we talk about protest, and why does this question matter? In this paper I consider the constituent parts of protest formation in the abstract, including grievances, gestures, and tactics, among other. Developing these constituent parts reveals protest to be, first and foremost, a manifestation of a nonhegemonic ethical commitment to justice, requiring courage and coordination, and whose outcome is always contingent, that is, an act of love. I also reflect on the nature of protest as a direct political action that sits on a continuum that ranges from opposition politics to civil war. This continuum offers a graded view ranking expressions of discontent by severity of outcome. (shrink)
