I’ve just read a very interesting and useful book by Ezat Mossallanejad, Religions and the Cruel Return of Gods.
Mossallanejad is a survivor of torture in Iran – torture under the shah, not the ayatollah. He escaped to Canada in 1985 and is a Counsellor and Policy Analyst with the Canadian Centre for Victims of Torture. The book is a scorching and thorough examination of religious cruelty and bullying around the world. It’s an immensely useful reference source because it goes region by region and country by country, covering most of them.
