Against the backdrop of the COVID-19 pandemic, anti-lockdown movements sparked concerns about online extremism escalating into real-world violence. This study takes the Australian anti-lockdown movement to explore extremist discourse in Australia, as it contained several, overlapping and interacting extremisms. This study explores the labelling of these protests as extreme and examines the interplay between individuals, ideologies and discourse. Understanding the definitions and labels of extremism is fundamental for identifying and countering potential threats, as it distinguishes harmful rhetoric from extremist discourse and enables precise, informed interventions. A qualitative close reading revealed that while Australian anti-lockdown discourse contained crisis narratives and group antagonisms, it did not consistently meet the structural definition of extremism. This is partly due to the problem of coding violence, which lies in the lack of a clear comparative threshold to determine whether a discursive claim, rhetoric, or cultural reference signifies violence or violent intent. While not meeting the structural definition of extremism, there was evidence of specific structural attributes that logically precede extremism and the emergence of violence. By reconceptualizing extremism as a temporal dynamic, this research explores the relationship between discursive and violent extremism, shedding light on the complexities of extremist movements and their social impact.
