Bringing together theoretical perspectives from both comparative politics and public law, this book examines the reasons why certain countries criminalize same-sex activities while others have carved into law the requirement that sexual minority communities be protected. The authors break new ground by using cross-national yearly data over decades—focusing on sodomy laws, death penalty provisions for same-sex sexual relations, and sexual discrimination practices—to develop a Gay Rights Index comparing treatment of such groups in various parts of the world. The book includes legal and large-N analyses, historical examples, and case studies underscoring important changes and key trends during the last several decades. Also highlighted are the significant human rights violations still being committed in various parts of the world against sexual minorities, and the continuing role religion plays.
