Censorship of books seem to resonate well with the right.
Unless there's a more specific example you can think of w.r.t rewriting.
Apparently children's books can't use the word "black" or "white" any more. And in the children's book "Witches", a witch posing as “a cashier in a supermarket” now poses as “a top scientist”. It's blunt-force rewriting by patronising leftists. Witches are not meant to be role models for little girls. It doesn’t matter where they work.
