There isn't anything surprising about this story. The return of diseases that we stamped out long ago is not exactly how the 21st Century was supposed to go. I figured that, by now, at least, we'd have dispensed with the anti-science and anti-vaccination arguments. Guess again.
When people who think they are smart are exposed for being dumbfucks, this is what they do. They double down and they don't care if their kids get hurt. That's a megalomania that has driven the world forever. Catching someone doing something dumb makes them either admit it or enter into denial and self-delusion. These are the times of self-delusion, and the irresponsible people who tout anti-vaccination ideas are always going to win a certain skeptical percentage of the population.
Facts and evidence aren't worth much anymore.
