In The Virus of Faith, Dawkins opines that the moral framework of religions is warped, and argues against the religious indoctrination of children. The title of this episode comes from The Selfish Gene, in which Dawkins discussed the concept of memes. The Root of All Evil? is a television documentary, written and presented by Richard Dawkins, in which he argues that the world would be better off without religion. The documentary was first broadcast in January 2006, in the form of two 45-minute episodes (excluding advertisement breaks), on Channel 4 in the UK.
