In this article, we investigate the relationship between loneliness and misogyny amongst the online movement of “involuntary celibates” (incels) that has become widely known through several violent attacks. While loneliness plays a prominent role in the incels’ self-descriptions, we lack a comprehensive analysis of their experience of loneliness and its role in their radicalization. Our article offers such an analysis. We analyze how loneliness is felt, described, and implicitly understood by incels, investigate the normative presumptions underlying their experiences, and critically (...) reflect on the political function of their discourse of loneliness. We claim that it is the affective mechanism of ressentiment that transforms loneliness into antagonistic emotions and show how loneliness is exacerbated rather than alleviated through the incel community. Finally, we point to the relevance of our analysis for contemporary philosophical and feminist loneliness studies. (shrink)
