This book investigates the growing politicization ofMumsnet and its use by politicians to influence middle-class women in the UK. The site's discussion topics go far beyond traditional 'mothering' subjects andencompass politics, feminism and current affairs. Understood as a safe spacefor gender-critical voices, the site has spawned real-life activism andcontinues to be both praised and attacked for its support of free speech oncontroversial subjects. Sarah Pederseninvestigates how Mumsnet has become a central part of a resurgent women'srights movement in the UK. She  arguesthat its openness to discussion around this subject has allowed the site tofunction as a subaltern counter-public - a space where gender-critical feminists have been able to share information andmake plans for action and agitation.
