My point is that she's not said what you think she's said.
She hasn't said that children of any kind shouldn't be helped. She's said that the current system, which works by saying the state has an obligation to give extra funding/help/accommodations to certain categories of child isn't just, and isn't working practically.
This is the simplest kind of example - we can see classrooms where a child with some kind of diagnosis of having additional needs being integrated is every day making the class ineffective and awful for the other kids in the class.
Why is what is supposed to be good for one child allowed to be the deciding factor, not what is good or bad for the other children? The reason is the school is legally obligated to provide for that child's needs, and difficult though it may be at times for parents to get that in place, there are processes to get it to happen. There are no such processes or rules to protect the other children in the classroom in the same way.
It's the difference between trying to produce outcomes as similar as possible for all kinds,and attending equally to all kids needs.
It's unfortunate that people, and organizations like those for parents of autistic children, are so myopic that they would rather defend a system that doesn't even work that well for those they are responsible for, before the discussion even gets to questions like, what would work better for all children and treat them all as deserving help.
It's not possible to develop solutions or a way forward without understanding what's not working now.
