States don’t like families, but even for a fascist state, “you’re too dumb to parent” seems like a bit of a stretch. Please note that the parent is not retarded in any way. The state just seems not to like her.
All I can say that a bureaucratic determination that one is “dumb” seems like an awfully slippery slope for the state to justify just about anything it wants to do. Indeed, I seem to recall a State that did just that: my great uncle (the one on the goyish side of the family) died in the gas chambers because he was gay and manic depressive. Apparently the Nazis really thought he was just too “dumb” to survive.
