I'm saying that Colbert was playing devil's advocate (no pun intended) the way he usually does, and Ehrman didn't exactly come off looking like he was making many good points. I realize one can only do so much in a short spot on a satire show and Colbert jumping on you every opening he gets, but if you profess to believe in these conclusions, and I certainly hope he does because he's influencing alot of vulnerable people, then you've got to hit some home runs once in a while if this is your life's work. Despite a cynical, secular, ever growing atheistic world, that feeds on sound bytes, the audience was drawn into Colbert's counter points. Call me crazy, call me a religious zealot, call me bias, but Colbert made some vaild points and did not come off insulting to Ehrman in any way. At one time, Ehrman believed that truth could be found, but the fact is, he was faced with what alot of Ex JW's and Protestants have found, and that is if one is intellectually honest and read early Church history, one either becomes Catholic/Orthodox, or one claims that the Church has manipulated or "cooked the books", ie, the bible and walks away from Christianity. Ehrman, and many others like him, have chosen the latter.
So the short answer is, no, it was not a real debate. I understand that. I've heard Ehrman actually debate with some seasoned Catholic apologists before, which doesn't happen very often, because the Catholic Church doesn't not rely solely on scripture to support their position. Ehrman will make headway with those (Protestants) that have to completely rely on Sola Scriptura (bible alone) to defend their position, but when the Catholic Church has the early Church fathers, ie the early christians, supporting their positions, Ehrman is left in a corner. And it's no wonder, he himself was a "bible alone" believer.
