[ilaksh]

The usual context for a question like this is actually finding out that someone has different beliefs from you.

First thing is for people to realize the prevalence of belief systems and how they are not derived or supported rationally.

Next thing is for people to realize that everyone has a belief system, no matter how non-religious or empirical they think their worldview is.

Corollary: Realize that you have a belief system, too, and therefore that, when the other person has different beliefs, they aren't necessarily the one who's wrong.
