Just on the fourth part now. To be honest I'm finding this all a bit one sided, even I could debate in favour for the Catholic church better than Anne Widdecombe and the John Onaiyekan. If they had put better debaters for Catholocism up there it would have been more equal in my opinion. They missed several key points that they really should have addressed.
Stephen Fry and Christopher Hitchens were only really bringing up predictable points about the Catholic church that you hear anywhere, in every debate. Widdecombe and Onaiyekan knew full well that these points were coming but didn't address them in their speeches, instead debating about the positive and leaving themselves as sitting ducks for the negative.
It's a shame because I think most people could have quelled half of the points that Fry and Hitchens made before they made them. When you debate you have to debate against the negative and for the positive, not just heavily on one and not the other.
