Not really. You claim that certain books should remain in the library even though the librarians of these private schools don't want it there to be accessible for reading.
Sounds like you are one of those nanny activists who want to impose your wishes on a school system, even a private one.
I say give the librarians the freedom to decide what takes up their limited shelf space. This is in no way censorship. Picking and choosing books is the responsibility of the librarian.
It appears that we agree on the issue since in this very same thread I have said that it should be the librarians, and not outsiders that decide what can and cannot be put on the shelves.
However, the most important thing here is that helping children develop not only reading skills, but the habit of reading in the most important issue. And if that means that kids read Harry Potter or Twilight, then libraries and librarians are succeeding in their work.
