Yep, it's all right here in the local fishwrap.
Let's define terms: a "Truther" (aka, "troofer") is a person who fails to test hypothetical propositions, then blindly accepts them, and touts them as being the truth, despite their untested and unproven status. These folk used to be called "true believers".
The best extant example of Truthers are those who believe that 9-11 was a government conspiracy, and the CIA blew up the Twin Towers, not Al-Q.
This particular group thinks that immunizations against common childhood disease can lead to autism because of a preservative in the compounded injections.
That's a double-whammy of "Troof". First, that ANY exhibited abnormal behavior in a child is now labeled "autism" by these folks (aided and abetted by the "autism industry" about which I've written before), and second, that none of the exhaustive, scientific-method testing that proved the immunizations safe means doodly-squat to them.
If I was Superintendent of Schools down there, and a kid turned up in school with a communicable, preventable disease for which there are immunizations required, I would refer those parents to the Department of Human Resources with a recommendation that said parents be prosecuted for recklessly endangering the life of their child.
For those readers who dislike my way of dealing with this (involving the Gummint), allow me to point out that protecting the general health of the citizenry from epidemics IS a legitimate role of government, unless your idea of "government" more or less resembles Anarchy. I also don't think that giving a "religious exemption" for immunizations is a good idea, as the practice of religion GENERALLY may not contravene common law (there are specific exemptions, however).
BTW, if you wonder about MY creds to even expound on this subject, my father held a physician's Certificate of Public Health from Harvard Medical School, and over my life from birth to 50, I listened carefully to his expertise and soaked up quite a bit of it.
