Is richard carrier loosing it?

Aparantly richard carrier has written: "But it's nowhere near as egregiously full of sh*t as Zeitgeist: The Movie, which has been thoroughly debunked as absolute garbage by several knowledgeable commentators" All i can say is that im loosing a lot of respect for richard carrier. If he had used arguments like those from zeitgeist the movie in his debate with william liar craig then im sure that the outcome would have been different. But no, he tried to lower himself to the xian level and argue on there terms. Lets hope christopher hitchens has the sense to bring up the plagiarism argument when he debates william liar craig.
