My evidence is your suggestion that MMR vaccination should be suspended so that mumps and rubella could again become widespread. Not gonna lie - I found the suggestion pretty infuriating. I don't think you explicitly meant "Hey, it would be cool if stik's kids dropped dead" but it was pretty clear that you were unconcerned about the consequences of those diseases for vulnerable populations. Which include my kids. And other children I care about.
I have no issues with kids who are at risk from MMR getting a vaccine, if their parents and doctor think it is warranted.
I do think mumps and rubella should be diseases one has in childhood - mostly for the life-long immunity. There has been an upswing in mumps cases in colleges recently and many women go to their first prenatal appointment to find out their titres for rubella are low. For me, it makes more sense for most of the population to get these VPDs in childhood rather than risk their immunity wearing off and getting them in adulthood (when they are far less safe).
I don't believe medical decisions for the masses should be made based on concerns for the few. Many pro-vaxxer don't either. Some will admit that certain subgroups of people should not be vaccinated (people we often do not know are a subgroup until they have a reaction) - yet we are not throwing out the vaccine program for a subgroup. Likewise, we shouldn't make vaccine choices for a subgroup.
As I know you are aware, my youngest is prone to pneumonia. I do not think everyone should run out and vaccinate themselves because she is prone to pneumonia. It is possible she belongs to a subgroup of people that should be vaccinated for certain things (pneumonia, for one), but no one else should have to assume the risks of vaccinating (well, her parents may choose to ) because of her health profile.
