Though widely seen as a privilege for religious actors, religious freedom under international law offers equal protection to those who are religious and non-religious, those who hold theistic, non-theistic, atheistic, non-religious or philosophical beliefs, and does so regardless of sexual orientation or gender identity. Historical and contemporary developments show how ‘religion’ or ‘religious freedom’ is often implicated in patriarchy, misogyny, bigotry, violence, wars, imperialism and mass atrocities. However, religious actors also play an important role in responding to humanitarian crises, assisting in development work, supporting social protection projects, opposing tyranny and oppression, promoting peace and conflict-resolution, and empowering oppressed and excluded voices, including indigenous peoples, women and LGBT+ persons, and refugees. As societies around the world have become more diverse with religion playing an increasingly prominent role in public life, often leading to what have been called ‘culture wars’ and ‘conscience wars’, the tasks of ‘right-sizing religion’ and reclaiming equal rights for all have become more urgent. This module responds to this challenge given that engaging with aspects of ‘religious freedom’ has become both unavoidable and crucial not just to public policymakers and duty bearers, but also for human rights advocates and academic researchers.
