I do agree that Ruby would benefit from opening her mind to a wider range of literature (and views about the world). Even if she intends to do an MA in Children's Lit it would do her no end of good to explore and engage with other texts.
As to your points about Lady Chatterley. I agree to an extent: it is important to view texts through the lens of the time they were writing. In its historical context, it's an important book. As to it being a good story.. had DH Lawrence not dehumanised Sir Clifford over the course of the novel and said that he essentially deserved what he got on account of his paraplegia, I wouldn't have felt it necessary to read up on his view of euthanasia and eugenics. When an author's politics shines through with so bigoted a light I find it hard to see the story as a good/ enjoyable one.
I know this is a massive tangent from talking about Ruby, so thanks for taking time to share opinions. I often think there are more interesting discussions about literature on this thread than on Ruby's GR page.
