<p>Anti-feminism has become a visible feature of Chinese digital platforms, yet existing research focuses mainly on its framings of feminism rather than on the masculine identities it helps to produce. This article examines anti-feminist talk in 12 male-dominated WeChat groups as a discursive technology for assembling a specific masculine identity, termed the “injured man.” Drawing on 571 chat records (2024–2025) and critical discourse analysis, the study identifies four recurrent formations: “calculative women” who weaponize intimacy and “free-ride” on men’s labor; “ordinary men” recast as the true victims of contemporary gender and class orders; fantasies of withdrawal and punishment articulated as moral justice; and rational-pedagogical performances in which anti-feminist speakers claim to offer objective “life advice.” Across these formations, narrated injury does more than express grievance: it operates as authenticity capital, a credential anchored in economic and emotional precarity that authorizes men to judge feminists, “modern women,” and the social order from a morally and epistemically elevated standpoint. In a post-socialist, nationalist and demographically anxious context, this authenticity capital enables a scalar move from “loser” to vernacular guardian of family and nation, while displacing attention from labor regimes, welfare retrenchment, and institutional sexism. The article argues that analyzing injury-as-authenticity-capital is crucial for understanding how platformed anti-feminism in China stabilizes symbolic and discursive violence, and for rethinking how feminist critique can engage with male grievance under constrained media conditions.</p>
