Catching up on it now - debating with Webberley is like trying to nail jelly to a wall. She is also quite thick.
On the Lesbian Podcast (I think straight women can listen, I hope <grin>) this week, Julie Bindel briefly mentioned the debate, and said that she was having to rethink her atheism, because she became convinced she was in the presence of evil.
I don't think Webberley is evil (or if she is, it's a by-product) ; she's just extremely stupid. She has no capacity for abstract or conceptual thinking.
