I don't want to be insensitive to the children, that have little choice on whether they are vaccinated or not, or more responsible relatives that would have vaccinated these children if they could have, but isn't this just natural selection at work in our modern society? How is this any different than parents that smoke around their kids or don't put them in the proper restraints when in a car? The parents, who either because of their intrinsic intelligence or because of the beliefs of their social groups, etc, choose to not protect themselves and their offspring from danger. Because of this, they can be removed from the gene pool, and this alters the future generations, hopefully for the better.
