For more than a decade, the destructive and dishonest ideology of radical feminism has flourished in North America.

In this provocative book, Neil Boyd argues that a new wave of self-described extreme feminists have been remarkably successful in reworking criminal and family law and thus transforming the rules of sexual conduct and our notions of fairness and equality, as well as undermining a socially valuable feminism. Boyd describes how U.S. radical feminists Catherine MacKinnon and Andrea Dworkin have been instrumental in changing Canada's obscenity law, shatters the various myths about domestic violence, and illuminates some disturbing truths behind sexual assault and sexual harrassment in today's society.

Backed up by extensive research and illustrated by stories that are chilling, Big Sister shows how extremists have changed the law in ways that threaten free speech, bring a code of Puritanism to male-female relationships, alter common-sense understandings of sexual consent, infantilize women, and jeopardize gender relations.
