It looks like maybe the agenda is to make autism the parents' fault. Then those elite, genetically superior upper crust folks can demand that morally inferior parents who damaged their children take on the burden of supporting, and maybe hiding, their mutant offspring.

As an additional bonus, the diagnosis of autism becomes a moral fault of the parents, something to be avoided if possible, hidden if not. Another lever to use on people, like being gay was up to the 1980s, or having African American ancestry was until the 1970s.

Not the parents’, specifically the mother’s fault.
