I wholeheartedly agree with you that taking the time to really connect with an individual so that you can then grapple with their beliefs from a place of deep, shared understanding is more ideal.
The problem is most of the scientific community is telling us that we're heading towards dire circumstances in the next few decades. I don't think we really have the time to hold everyone's hand and bring them gently to the realization that we're all part of a massive problem that could very well threaten the continued survival of our species :(
