nooka, Enid Blyton wrote within her times. If you don't like the 'racist' bits, then avoid those particular books.
It isn't conducive to an understanding of people in general to make such sweeping statements. Enid Blyton was writing before the Windrush came into town, before mass immigration. Her only experience of black skin would have come from tales of derring-do, when missionaries were 'cooked in cauldrons'.
The golliwogg is a Dutch invention, in the European sense. It is argued that it was 1/ just another rag doll but this time with a black face, and 2/ a racial slur on black people. The Dutch celebrate Christmas with St Nicholas (sp) .. who is our Father Christmas, and Schwarze Pete (sp), a little black-faced boy who was his help-mate. It isn't a big leap of the imagination to create a black, rag doll.
For what it's worth, I had a gollywog when I was a child, and it never crossed my mind that it was the racist personification of evil. It was just another rag doll, like my white rag doll. Equally adorable to me.
The jury is still out, and it always will be.
