A core principal of a martyr is being widely liked. No one gives a shit about this dude. Even the people who he surrounds himself with don't give a flying fuck about the dude. Musk himself makes every interaction with him transactional. Add in his default behavior of being an 11 year old edgelord wrapped in a 50 something whale body with hair plugs that's awkward as fuck to be around, and yeah it's not hard to see why nobody likes this fucking billionaire with attachment issues.
Dude needs to ditch the ketamine and perhaps get actual therapy. And actually having a better diet and exercise regimen wouldn't hurt either.
It's because these people are poorly educated. This group of Mennonites is very back woods thinking. There are zero ways they will ever trust vaccines.
You ask what percentage of kids it will take? 0% All of their children could die and they would chalk it up to God's will and get busy on making more.
Most people cannot comprehend just how backwards some of these groups are but think of life early 1700s. That's what you are dealing with. No one can convince these people anymore than someone can make the sun set in the East.
There is nothing that can be done about these people. Hell some don't even speak English, they still speak the old low German language. Like this couple they speak a broken mix between 1700s German and English that's developed in that area.
I cannot stress this enough, these people are never going to vaccinate. The cost of life is completely irrelevant in this aspect.
