Earlier quoted context omitted.
I've read a few older books with my kids that contained mildly questionable things, like a boy saying that girls can't do certain things, but I much prefer having that awkward conversation about how things used to be, over tossing it all out and pretending things were never any different.
As someone once said about the controversy surrounding Mark Twain's books: "so there weren't any n** back then?" Meaning that reprinting his books and replacing the n word with the more neutral "slave" risks whitewashing the terrible suffering that black slaves endured.
Also, theres a lot of presumption, thinking you can rewrite a classic author just to fit your modern sensibilities.
