I guess I was more looking for texts where the Buddha interacts with somebody who doesn't agree with him. I'm curious about the ways he handled such situations.
If you're really all that curious, you ought to pick up translations of the
Majjhima and the
Digha Nikayas, and begin reading through them. You're sure to find something of what you're looking for, in addition to being exposed to quite a bit of information on what Gotama thought about a variety of things and the way he responded to those who questioned him.
One discourse that comes to mind is MN 71
Tevijjavacchagotta Sutta where Gotama denies possessing complete knowledge of everything at all times and defines the three fold knowledge he does possess. The exchange takes place between himself and the wanderer Vacchagotta.
Another discourse in a similar vein is MN 72
Aggivacchagotta Sutta, where Gotama explains to the wanderer Vacchagotta why he does not hold any speculative views. Vaccha asks questions and Gotama responds. With the simile of an extinguished fire, Gotama tries to indicate the destiny of the liberated being.
In the Digha Nikaya, there are DN 11
Kevaddha Sutta and DN 13
Tevijja Sutta. In the former, Kevaddha urges Gotama to perform miracles to strengthen people's faith. But Gotama refuses, saying the only kind of miracle he approves is the "miracle of instruction." He tells the story of a monk who wanted to know "where the four great elements cease without remainder." By psychic power the monk ascended into the heavens, but none there could tell him — not even the Great Brahma, who referred him back to the Buddha for an answer.
In the latter, two young Brahmins are puzzled because different teachers speak of different ways to attain fellowship (or union) with Brahma, which to them is the highest goal. Gotama gets them to admit that none of their teachers, or even those from whom the tradition stems, have ever seen Brahma face to face, then instructs them in the Brahmaviharas, which do lead to that goal — which is not, of course, the goal of the Dhamma he teaches.
I'm sure there are other discourses within these volumes which portray Gotama in discussion with those who either disagree with him or are seeking his opinion on certain points, but off the top of my head they don't come to mind.
