The treatment of sexual minorities—whether lesbian, gay, bisexual, or transgender—varies significantly in different parts of the world. In some countries, equal rights have been achieved and progress is being made against discrimination; in others, being gay still incurs the death penalty.This guide examines all the colors of the sexual rainbow, unearths hidden histories, and looks at contributions from medicine and science. It also includes a unique global survey of laws that affect sexual minorities. Vanessa Baird has been co-editor at New Internationalist magazine since 1986. Her previous books include, as compiler and editor, Eye to Eye Women.
