To achieve gender equality, we’ll have to engage men. Above all, because gender inequalities are sustained in large part by men – by men’s attitudes, behaviours, identities, and relations. First, this work must be feminist – and I mean, strongly, robustly feminist. Second, this work must challenge men. It must address male privilege. Gender inequality is as much a story of male advantage as it is a story of female disadvantage. Gender inequality is a story of male privilege. Third, we have to involve men in processes of personal and social change. Fourth, we must affirm diverse ways of being a man. We should affirm men who do not fit dominant codes of masculinity and challenge sexist constructions of manhood. Finally, we have to engage men in working for systems change. In tackling the material, structural, and cultural factors that underpin gender inequality.
