Strictly speaking, if we're talking about current beliefs there may not be enough time to discuss them, because depending on how long the discussion is it may no longer be current - so much so that if you're keen on discussing them you may never get anything done!
It's funny that the ability to hold on (or be attached ) to beliefs is valued and respected, so much so that even when people disagree it's like the worse thing they believe they can say is "they don't believe in anything" - which is something a fundamentalist like JWs have said about Unitarian Universalists, for example. With that kind of mentality it's like even if they strongly disagree they have at least some respect if you believe in something, even if it is blind belief.
From a practical perspective it's easy to understand that beliefs are conditional, you can try on a set of ideas about things and see what works, but be ready to change if it doesn't. From this perspective that kind of attachment doesn't make sense, and yet we apply that kind of attachment not to practical matters (there may be immediate feedback to prove it wrong or dysfunctional) but with things like how we view ourselves and reality! When we honestly look at beliefs this way it is not only obvious that it concerns matters that is not likely to be tested, but often we find that the individual is rather insecure about those ideas.
Of course, what seems to happen is we forget that the view of ourself is a view, but actually take the thought as who we are rather than the mental activity that it is. Being that it is an activity, we can change it. So it really makes sense to pause when someone might be inclined to go from one identity to another: Doesn't the fact that you can change your beliefs make you question whether you can consider an idea what you are, regardless of what it is? It's like if you were able to change shape physically, you wouldn't seriously consider yourself the new shape that you took on, would you? You know that's just a form you've created, it'd be rather ridiculous to live like you're that form and get worked up when that identity is questioned, because it is by nature temporary. People speak in terms of re-creating themselves, and while I think that's great it's also just kind of silly to think of that as yourself. Not to dismiss the energy they put into getting an education and such, but clearly what people think is something they do rather than what they are.
You are not your beliefs, you are the one doing the believing.
