Why are we so closed-minded, esp. in religious matters?
Though a believer myself, I address a lot of questions to atheists. I ask to hear their point of view.
It is NOT to convert them or put them down in any way.
You can learn more from your adversary, they say.
'Preaching to the converted' is a usage in English.
It means addressing people who already agree with one's opinions. What is the point? There is not much learning there.
We may have much more to learn from an opposing point of view. Yet, why do we remain so shut mostly? Why so?
