I think it is good in a way. You're not going to convince them of anything in that ten minute bus stop conversation, not should you try. But it's good for them to have the experience of talking to someone who doesn't believe in their thing, and it's good for both of you to interact with someone you don't share a belief with but still experience them as a person. On the Internet we tend to protect ourselves from the other by replacing them with a caricature. Regardless of who's right and who's wrong that can become a pretty toxic habit.
