I hope we have a moratorium on disasters for a while, so we can (hopefully) reset. I think it's high time that we start to udnerstand better how we as people work in the (new) environment we're finding ourselves in, where increasingly our tethers to society are more and more unreliable (I'm thinking of social media, though that's not the entirety of it). I don't think the people pointing fingers and laughing are being fully sympathetic to how much these people's world view is being challenged, and I think that the more "kind" we can be to some of these people the better chance we have of increasing our collective understanding. It's high time that we reject this idea that "you don't agree therefore you're dumb, deplorable, and my mocking and marginalization is fully acceptable", which of course ASSUMES we know why they disagree, and start to have the first step be "why do you disagree, what is driving that?" so we can have more meaningful dialogue.
Just by way of example, I'm in no way, shape or form an anti-vaxxer, but I do, kind of, understand it. My stepson - who I love and admire - is on the spectrum, and I watch his parents struggle with that every day in every way, INCLUDING finding answers as to "why" (it doesn't help that one of them is as insecure as a screen door in a hurricane; for him, every "answer" is predicated on "mom is a c***"). People NEED answers to things that don't always have answers, and we are by our nature "trained" to see patterns, even when there are no patterns. Yes, education - and so much of education is REPETITION - would help, but how many of us are secure, aware, and disciplined enough to say "I have a world view, and even though it's my belief, I know it's wrong, so I'm going to literally retrain my brain to be 'right'?"
