Big Sister is an unsparing look at radical feminism and its effect on society's judicial system. In this provocative book, Neil Boyd argues that a small band of female extremists has been remarkably successful in reworking criminal and family law. Now that radical feminists have moved into positions of influence as lawyers, judges, politicians, and policy makers, their thinking can be seen in decisions across the legal landscape. He argues that there has been an erosion of the rules of sexual conduct and our notions of fairness and equality, and an undermining of a socially valuable feminism.
