Earlier quoted context omitted.
I recent came across a technique for having a more substantial discussion and it was to ask: "Well, what would it take for you to change your mind?" Not that this is a silver bullet that automatically leads to peace and harmony, but it's a step in the right direction.
That question might best be prefaced with “here’s what would change my mind… what about yours?” That formulation might come across as more curious and open rather than patronizing. Though I honestly don’t at all understand the mindset of people who don’t want the vaccine, so I have to admit this approach could quite easily still be offensive.
Understanding that base fear will help bridge the divide between groups.
