The paper explores the re-emerging conflict within feminist community revolving around the attempts to exclude trans women from the feminist movement. Feminists advocating for the trans exclusion claim that trans women’s interests and goals are allegedly in conflict with cis women's rights. Trans-exclusionary feminists label trans women as threat to cis women's physical safety, while trans men are being viewed as passive victims of the patriarchal oppression of cis women. The central question in the conflict is the relationship between sex and gender, greatly influenced by the work of Judith Butler. A similar situation to that seen in the West is currently present in Serbia and Croatia, where the conflict has become more intensified following the appointment of trans-exclusionary feminist as a new executive director at the Zagreb’s Centre for Women’s Studies in December 2020. Despite their attempts of employing a Marxist analysis, which include the interpretation of sex as an immutable biological/material fact, trans-exclusionary radical feminists find themselves sharing the same position as conservative actors. Trans-inclusionary feminists and LGBTIQ+ organizations are showing that cis women and trans persons have the same interests in the struggle against patriarchy and capitalism.
