Against Ageism: A Queer Manifesto starts with what it is not: a socio-economic argument against ageism, celebrating the ‘elderly’ as economically viable. Instead, Simon(e) van Saarloos presents a radical critique of conventional arguments against ageism, rejecting constructs of ‘age’ and ‘youth’ and assumptions of their inherent qualities. Drawing from personal experience, the manifesto offers a reckoning with how ageism overlaps with structures of white supremacy and patriarchy. Through the lens of crip and queer theory, as well as anti-carceral and anti-colonial perspectives on time, this piercing text provocatively calls for the abolition of age-related laws, reframing commonly held understandings about age from van Saarloos’s defiant perspective.
