This episode begins with a discussion of why a separation of church and state has been historically valued. It explores the effects of stereotypes and over-generalising, and the effects of religion on establishing secular ethical values. The episode also addresses how religions can divide society, and the dilemmas we face when religious practices run counter to secular ethical principles, or to the ethical principles of other religious groups. It concludes on a distinction between tolerance and acceptance of other religious beliefs (or no religious belief).
