This paper redresses the neglect of interregimatic solidarity—solidarity between collective anti-oppressive struggles in purportedly antithetical regimes—in transnational feminist scholarship. I argue that authoritarian and demostatist regimatic contexts of oppression give rise to regimatically distinct oppressive kinds, which track their regimatic subjects of oppression respectively, and that this fact significantly increases the risk of interregimatic missolidarization in lieu of interregimatic solidarity. In response, we need to cultivate antiauthoritarian resilience, which is both an epistemic virtue and a moral virtue. Epistemically, it (...) helps us navigate a world characterized by the dynamics of authoritarian spillover, demostatist sellout, imperial standoff and capitalist scaleup, comprehend how regimatic oppressions are interconnected, and appreciate the practical import of interregimatic solidarity. Morally, antiauthoritarian resilience helps us discern and discard moral parochialism and cynical moralism, both impeding the exercise of interregimatic solidarity. I conclude with tentative thoughts on when, for whom and to what extent interregimatic solidarity is morally obligatory, if its realization depends on cultivating the virtue of antiauthoritarian resilience.
