>The purpose of moralizing is to shame those that ignore our struggle as living organisms.
So how is that working out?
Think of all the campaigns that have effected change. How often did shaming work? Sure, you have a few cases like the fight against Apartheid, but in general? Not effective.
Here's the thing. I'm as pro-science as they come. However, I've been blessed to come from communities that fall prey to anti-vaccine and other "nonsense". And one thing I know is that fact based ridicule and moralizing has a low success rate.
As someone who somewhat understands both communities, I am already not on your side. If a pro-vacciner like me is turned off by such rhetoric, imagine it from an anti-vacciner's side.
Think I'm an outlier? I'll hazard a guess that most pro-vacciners are close to someone who is not (family connections, etc).
There is comfort in being "right". But being "right" does not in itself translate to right outcomes.
The Righteous Mind (https://www.amazon.com/Righteous-Mind-Divided-Politics-Relig...) is a very worthy read. A few things it points out:
1. On a polarized issue, facts will increase the polarization (and I'm guessing justifying shame with facts will exacerbate the issue)
2. To persuade someone, you will have a lot more success appealing to emotions than to the rational mind. This does not mean playing games where you manipulate people.
