This book offers a critical discourse analytical perspective on the phenomenon of men who voluntarily abstain from relationships with women. Based on a case study of the online Reddit community known as ‘Men Going Their Own Way’, the author engages in qualitative examination of the argumentative and discursive strategies used to justify and legitimise an antifeminist, male separatist ideology. Methodologically, the book draws on the discourse-historical approach to critical discourse studies and investigates how members of this online community represent themselves, relationships with women, and the broader gendered social order. It considers male separatism as part of the new antifeminist social media network known as the manosphere, as well as part of a broader legacy of backlash against feminism and women’s rights. Overall, the book contributes to the growing body of literature on the manosphere and should be of interest to scholars in discourse studies, feminist media studies, and digital communication.
