I'd love to hold society to the standard that no child should have to risk death due to parental stupidity. That's just not California. If you really want to uphold this ideal, you'll have to crusade for myriad causes, including gun control, obesity-fighting measures, tighter distribution of driver's licenses, promotion of breastfeeding, etc, etc. On the list of annual deaths in California caused by parental stupidity, lack of vaccination is near the bottom of the list.
All of this is true. However, lack of vaccination will rapidly climb the lists if America's current anti-science, anti-education and anti-logic trends are allowed to continue.
