The Debate considered the motion “The Catholic Church is a force for good in the world”. Christopher Hitchens and Stephen Fry, opposing the motion, comprehensively trounced Archbishop Onaiyekan (of Abuja, Nigeria) and Ann Widdecombe, who spoke for it. The archbishop in particular was hopeless.
The voting gives a good idea of how it went. Before the debate, for the motion: 678. Against: 1102. Don’t know: 346. This is how it changed after the debate. For: 268. Against: 1876. Don’t know: 34. In other words, after hearing the speakers, the number of people in the audience who opposed the motion increased by 774. My friend Simon, who’s a season ticket holder, said it was the most decisive swing against a motion that he could remember.
