Several scholarly works have identified the weakness of mainstream social science and the humanities to theorize racism. The sociology of absence grasps the systematic exclusion of specific experiences and specific voices within social theory. We are inspired by these contributions in our exploration of the role and the location of the category of residents racialized as not belonging to the Swedish nation, in anti-racist struggles. We are also inspired by the scholarly tradition that explores the relationship between haunting, ghosts and social justice. As a complement to the concept of waves of anti-racism, we use the concept of ‘critical event’, identifying events that challenge and transform existing frames of interpretation regarding racism. In this chapter, we focus on three critical events: the 1990 Karl XII neo-Nazi celebrations in the city of Lund, the 2000 “Kämpa Showan/Kämpa Malmö and finally, the solidarity crisis in the 2016 at Malmö Central Station. The empirical material is crafted through a patchwork of sources, being participant observation, in-depth interviews and two focus groups with anti-racist activists, identified as “second generation” participating in anti-Nazi/anti-racist mobilizations.
