This was my thought as well.  Critical thinking requires one to recognize that not all opinions are valid, some are based purely on emotion or pseudoscience and to equate them with well thought out and reasoned responses to facts is just simply wrong.  If people really believe they have the right not to vaccinate their children, then public health should dictate that their whole families, not just the unvaccinated be segregated from the general population.  Why should the general population be put at risk for their personal decision?
