Okay my first point would have to be to let you know that,
Did you know he has a criminal record in fraud? It is interesting from a moral standpoint.
Secondly thank you for showing me this video as it has re-inforced my opinion on my atheism

I think you had the standpoints the wrong way round.
Everything D'Souza had said, Hitchens shot down with a smile on his face. On numerous occasions during that debate D'souza admitted his mistakes on what he had said and Hitchens made no mistake in what he had said.
One other thing is that I'm stuck on where D'Souza stands on his viewpoint? Does he believe in evolution as well as a god. Because the way I listened to him, he seemed to be rationalising Evolution and putting evolution down to the work of a god.
Another thing I noted was that he didn't take his argument from the standpoint of what he believes, but targeting what Hitchens believes putting it as "approaching him on his own ground". Why is this? Why not argue from his own ground?
I would put that down to D'Souza being intolerable on questioning his own beliefs. But even he said If we show him evidence of the big bang and so forth then his opinion would change away from a god.
Doesn't sound like faith to me, More like siding with the winner

and as Hitchens said that's corrupt belief.
I am eager to hear your reply Blade.
EDIT: During audience questions, D'Souza didn't really answer the first question, During the second question he again didn't answer what was asked, Only threw blame unto Atheists via comparing death statistics.
Although obviously quite intelligent, He didn't really shoot down anything. Just tried to disprove Hitchens and fill the gap with, Only Intelligent design could have done it.
The good old, "We don't know what did it - so it must be god"
