Well, what I mean is, why would we want to change someone else? Isn't it because we disagree with some facet of their lives? If we want to change them, then there is something we don't like that they do, right? And if it is something we don't like, then it is contrary to what we think is right and we object, thus we debate them and/or manipulate them to get them to change.
But think about this...(just an analogy) let's say someone you know suddenly becomes a vegetarian. And each time they see you, they would make comments about eating meat. Asking you questions...what did you eat today?
After a while, you will certainly tire of that because you have no intention of not eating meat no matter what. But think about it from their vantage point: they see eating meat as torture and murder of the animals God created. Maybe you don't. That's fine, but if their motive to change you is out of love and compassion, then that should be respected.
So I guess if the motive to try and change someone else is out of love and compassion, then it's cool to just listen and try to understand. We are not obligated to change for anyone, but we should be honest with ourselves that maybe it is we who need to change.
