What drives incel ideology in Canada?

Monday's shooting in Montreal has focused attention on the incel — or involuntary celibate — movement, after it was revealed that the suspect in the shooting apparently distributed a 104-page manifesto full of hateful commentary about women, but also criticisms of capitalism and calls for violent revolution. We talk to Esli Chan, a PhD candidate and researcher at McGill, about how that manifesto echoes the kind of ideology that circulates in online incel communities… and what authorities need to do to prevent further incidents of violence.
