In an age of intolerance where religious persecution is widespread, Barbara Ann Rieffer-Flanagan explores how societies can promote freedom of religion or belief as a fundamental right of citizens Examining the extent of religious persecution throughout the world, this cutting-edge book explores mechanisms to address religious intolerance and develop religious freedom, outlining the necessary factors to measure progress on the protection of this fundamental human right. Chapters explore how freedom of religion or belief can be institutionalized in dispositions, laws, and policies through efforts which limit negative depictions of the religious (or non-religious) Other in public discourse. Rieffer-Flanagan demonstrates how reforms that enhance the ability of civil society actors to operate can also promote freedom of religion or belief, and how states and IGOs can support these efforts. Ultimately, this innovative book proves that reforms must be continually nurtured for freedom of religion or belief to exist in society. With interview-based research and a diverse range of regional case studies, this will be a vital resource for students and scholars of philosophy, religion, human rights law and political science. Considering the role of leaders in the promotion of religious tolerance, the book will also prove invaluable to policymakers concerned with human rights and freedom of religion or belief.
