A reasonable response to anti-vaxxers

There will come a day when our children or our children's children will read about the anti-vaxxer movement and say, "What was wrong with you morons?"

I will say, "In the early twenty-first century, Americans read about a study in a British medical journal that claimed that vaccinations caused autism, and when that study was completely debunked a short time later, they didn't care, because they were ignorant, selfish, and had too much time on their hands. Also, some C and D level celebrities, as well as the President of the United States (also a C-D level celebrity) had taken up the cause because they, too, were stupid, and Americans loved celebrities." 

Until that day, this is a fairly effective response to the anti-vaxxer movement.
