Thanks for that link, BTS. I'll watch that in the next day or two. Here's a quote from someone who attended:
For those who couldn't be there, here's a summary of D'Souza's arguments, more or less in the order presented:
-Religion isn't bothering you, so leave it alone. Do I persecute unicorn believers?
-Atheists (i.e. Stalin and Hitler) killed more people than Christians
- Christians like Mother Teresa did more good things for the world than Atheists.
-All these different scientists/artists/musicians were Christians, so Christianity must be okay
-Just look at the complexity of the universe and the way the "dials" are set perfectly for us, therefore Jesus died for your sins
-Science can't know a 100% absolute truth (i.e. the problem of induction) therefore the miracle of the resurrection is true
-Evolution can't account for human morality and altruism
-The reason why atheists are militant is that they--like Hitchens--hate God. Probably it was some kind of past trauma.
-A society can't survive without religion.
-Mother Teresa was awesome, therefore Christianity is a good thing
Hitchens started out really strong and had a good opening presentation, but then he got bogged down in an argument over whether Christians or Atheists had killed more people in history that went nowhere. Then he kind of lost interest in the second hour and let D'Souza run away with emotional rants (Hitchens was getting pretty slurry toward the end too--that wasn't water he was drinking). So I'd say that D'Souza "won" the debate in the sense that he did a better job of presenting his (tired and lame) arguments. Hitchens wasn't strong on the physics or biology (didn't even correct the "biology can't account for morality" claim) and once D'Souza noticed that, he went for the arguments that Hitchens was weak on.
But the crowd seemed about 50/50, even though it was sponsored by a Christian power college, and maybe some people's minds were changed.
Brother Apostate has pasted some of his arguments and I didn't find them that challenging - the whole 'in the name of atheism' stuff, for example. Maybe there's better stuff he's written, but I haven't seen it yet.
