Unfortunately, vaccine injury is often labelled "autism". What is known as "isolated autism" is in fact vaccine injury. "Isolated Autism" is where a child was walking and talking and had no other health issues (no mental retardation, no seizures, etc) and SUDDENLY after being vaccinated (or sometimes another big environmental assault like anesthesia) they change and become very sick and lose abilities like talking and may start head-banging, etc. This is INJURY and not neuro-diversity. Yes, some children seem to be born different/autistic, but MANY, MANY suddenly become ill and then get labelled as "autistic".
There is a bit of a movement amongst parents who recognize that the so-called "autism" was caused by vaccines, to stop calling it autism and simply call it vaccine injury.
Much hostility comes from people who really are "neuro-diverse" against people who say vaccines (or something else) caused my child to be autistic and I want to change/heal them. The people who want to heal/change their children truly have SICK CHILDREN and the doctors have labelled it as autism. So the parents call it autism. And then the truly neuro-diverse get offended that someone wants to "FIX" them. But of course any parent with a child who is sick wants to fix/heal them.
I find it so sad that the system/media has pit these groups of people against each other and that we all fall for it and keep fighting. They want this "Autism" issue to be polarized. Let's try to understand each other instead and that we are doing the best that we can.
