I think this is Nature's way of reducing the population of stupid people. If you're too dumb to listen to the advice of scientists, you're probably too ignorant to survive in modern society. I feel sad for the waste of humanity but I have no control over your stupidity.
The issue is that it's impacting the children of stupid people (who very well may already be vaccinated). I find it difficult to rejoice in the suffering of innocent people for the actions of another.
