Regarding the ability of literature to lock children into a POV, I'm old enough to remember the panic over the
Heather Has Two Moms sort of book. And thirty years later, rather than the two moms set having taken over, I'm reading
Where have all the lesbians gone?
Even if my last link is exaggerated, the earlier campaign against freedom to read gay-friendly children's books failed to understand the role of literature, as does this one.
Did Theodor Seuss Geisel want to convince African-American children that they should move to Africa and become hunter-gatherers? I doubt it. But if he did, he's been wildly unsuccessful.
Suppose the Geisel family finds an unpublished Seuss manuscript titled
How to Poison the Non-White Kid in Your Class. Should they seek out an extremist publisher? No. But that's not the range these freedom to read kerfuffles ever get into.
