This text presents an analysis of some aspects of the phenomenon of so-called incels. It focuses on the sexist and male supremacist ideology inherent to the incels’ narrative. It also follows a link between this ideology and the assumptions made by some commentators on the incels’ problem, who have been relying on a mixture of conservative views on society and reductionist naturalism. I present a critique of these background assumptions, relating to concepts that feature centrally in them. First, I criticise (...) the characterisation of a particular concept of ‘monogamy’ as natural and its possible construal as normative. Then I explore the rhetoric of sex as a ‘basic need’, pointing out the tendency to mistake what one wants for a ‘need’. I conclude by criticising the particular kind of idea of the science of human nature that underpin the reductionist accounts of sex-related violence. (shrink)
