Last year, I made reference to the vaccination vs. Autism controversy, which is probably a misnomer, since controversy indicates that there is a difference of opinion. Science is not like that, scientific theory eventually becomes fact through rigorous testing and evidence based analysis.
But parents are not scientists and are swayed by qwacks and disinformation as evidenced by much of what follows the McCarthy b.s.; although with her working on The View may now be in a completely different direction.
Why not vaccinate? These out of left field approaches are very much affecting us all, not just the poor kids that have to struggle through whatever illness that could have been avoided.
Just as the Dawkins article suggests, we need to actively counter the misinformation with facts, such as the thimerosal points in his article.
