The conversation which takes place between the members is as follows:

“Yeah, but Atticus aims to defend him. That’s what I don’t like about it.”
Here, readers can easily come to understand how the citizens of Maycomb feel about Atticus defending Tom Robinson.

Readers find out about the conflict through Scout's statement:
This was news, news that put a different light on things: Atticus had to, whether he wanted to or not. I thought it odd that he hadn’t said anything to us about it—we could have used it many times in defending him and ourselves. He had to, that’s why he was doing it, equaled fewer fights and less fussing. But did that explain the town’s attitude? The court appointed Atticus to defend him. Atticus aimed to defend him. That’s what they didn’t like about it. It was confusing.
Here, readers see the conflict. Even though Atticus was appointed to Tom's case, many believe that he should not out as much effort into defending the African American. Atticus, taking every case seriously, decides to defend Tom to the best of his ability.
Therefore, readers find out about the conflicting values between Atticus and the town by how each percieve Atticus' appointment to the case.
