In the concluding episode of this two-part series Richard Dawkins asks why, despite science having exposed old religious myths, militant faith is back on the march? The mechanism for perpetuating beliefs that Dawkins describes as leading to murderous intolerance, is by imposing religion on children who are too inexperienced to judge it for themselves. 'We wouldn't categorise children according to their parents' political stance', says Dawkins, 'since they are too young to make up their minds about such matters. But we segregate them in sectarian religious schools, where they are taught superstitions drawn from ancient scriptures of dubious origin, which promote a contradictory and poisonous system of morals.'
