In my analysis of manifestos collected from 1966 to 2025, gender identity-driven violence appeared in nearly 40 per cent of them. These violent beliefs were either the primary or a significant secondary motivation for the attack. This includes direct expressions of hatred toward women, trans and queer people and references to feminist or LGBTQI2S+ movements. The Waterloo attacker did not explicitly identify as an “incel” (involuntary celibate), but the language in his manifesto closely echoes those found in incel and broader manosphere discourse. Feminism is portrayed as dangerous, gender studies as ideological indoctrination and universities as battlegrounds in a supposed culture war.
