The rise of Donald Trump and the resurgence of neoconservative political movements in the United States have reignited contentious debates about gender, power, and the rights of women. Under Trump’s leadership, rhetoric rooted in traditional values and a reactionary stance on gender roles have deeply polarized the political landscape. Feminist scholars and activists have responded with varying forms of resistance, from large-scale protests against the rollback of women’s rights to the radical re-emergence of gender separatism. This form of feminism, drawing from the theories of second-wave feminist giants such as Sheila Jeffreys [3], Andrea Dworkin [1], Kate Millett [8], Germaine Greer [2], Janice Raymond [11], Catherine MacKinnon [7], and Audre Lorde [6], has come to represent a counterpoint to the growing reactionary forces of inceldom [10] and the neoconservative backlash [14]. Movements like the 4B movement [4–5]—advocating for women’s rejection of male-dominated institutions—illustrate the resurgence of separatist ideologies in the face of increasing patriarchal control, epitomized by Trump’s administration [4–5]. Through the lens of feminist theory and cultural critique, this essay explores the revival of sex-based separatism in modern-day America, the implications of Trump's sexual divide, and the broader cultural and political consequences of the rise of inceldom and far-right extremism [10].
