Autism is a spectrum of unusual behaviors. If a kid exhibits enough of them they are given a diagnosis of autism. In and of itself, behaving differently from others is fine by me. I prefer the outcasts, the avant garde. In truth, autism is medically meaningless.
What is meaningful is parents, doctors and researchers have found that most autistic kids also have physiological ailments and most of those physiological ailments can be traced back to vaccines or similar toxic assaults. Many of the abnormal behaviors in autistic people are now know to be caused by physiological injuries. In fact, countless thousands of parents have watched their kids begin developing just fine, only to regress horribly after receiving vaccines. A growing number of these parents have recovered their children by reversing the damage done by the vaccines.
That some kids are born with the physiological deficits common in autism is due to the fact that their parents were already toxic before they were born and that toxicity was concentrated when it was passed to the child in the womb, or the mother was vaccinated during pregnancy.
Remember, autism is a spectrum. Some kids are more or less okay, with just some weird quirks. Others will never walk, talk, live without diapers, eat solid food, etc. Also remember, for those who suffer from autism and the attendant physiological ailments there are treatments. If a parent can accept that their child is not just unusual but actually has physiological illness, they can recover them.
To not do that seems like criminal negligence to me. To ignore the problem on the larger social scale is to commit generations, even all of humanity, to a terrible fate.
