I came across this piece today that exactly expresses my own view on what motivated Suzanne Wright. It applies to (some) grandparents as well as parents, and this exaggerated sense of entitlement is a cardinal aspect of intrinsically narcissistic personalities like Wright.
"And yet a third factor is the belief of many autism parents that they are entitled to a ‘normal’ child, and that it’s a huge affront, a violation of their ‘rights’, almost a crime in fact, for them to have one that isn’t. This is not an inference by the way, many of them outright say so, in very forthright terms that go way beyond ‘grieving’ into ‘grievance’. Their concern seems to be not for the child’s welfare, but for themselves. It’s as if they have this expectation of what their kid should be, how their child should reflect well on them, boost their social standing – so if their kid looks unlikely to ever be a cheerleader or football star, be ‘popular’, go to a prestigious (or any) university, bring home trophies, etc, etc, in short, if they have a kid they can’t show off, this is a ‘sin’ in their eyes. How this ‘I have a right to a normal child’ belief evolved, I’m really not sure, but those who hold this view consider themselves not only entitled to such a child, but entitled to do anything at all that will change their ‘deficient’ or ‘abnormal’ child into the one they believe they should have had from the beginning. They swing into action, blasting the child with every weapon at their command, and blasting too anyone who might have a different view of autism. They seem to hate autism because it disrupted the life they believe they are entitled to."
