Many hold strong beliefs and opinions, however not many know the roots of their belief. If a person agrees to explore it, both of you will learn something new and fascinating. The problem is finding someone who wants to think and ask the questions. This goes for both. Many want to “convince” someone, but how much do you truly know about the thing you’re trying to prove?
This also comes back to the “why?” game so many kids play. Parents get annoyed by it, but are they really annoyed at the game or their lack of knowledge depth? Play the game, find out how deep you lake of knowledge goes
this doesn’t guarantee that the conclusion is correct, or is in scope of expertise of either of you
It doesn’t, but at least it makes both think and hopefully improve the quality of the arguments. And with internet at our finger tips, it doesn’t take much to double check a couple things :)
That’s a part of the enlightenment and purpose for open-minded people. One or both may learn they really don’t understand what they so firmly believed.
