Can Censoring a Children’s Book Remove Its Prejudices?

Found this article at Nine Kinds of Pie talking about changing story content to reduce prejudices. Philip Nel uses Charlie and the Chocolate Factory and Dr. Dolittle in his article Can Censoring a Children's Book Remove It's Prejudices? What is your opinion on the concept of removing or changing content? After reading this article, what edition of the book would you read to your child or student?

Loved This Book!

When I was in elementary school, I used to check out the same book over and over from the County Library. The book was called The K House Mystery. At first I couldn't find information on this book and could not remember the author. After intensive searching I finally found information on this favorite book! I was surprised to find that this book is the second of two-part series. My desire is to track down and read both books as a series. The McCoy Memorial Library in Illinois describes both books follows: 

Seven Go to Eastcroft, [by] Grace Trobaugh Hay. Illustrated by Sherman C. Hoeflich. Philadelphia: David McKay Company; Washington Square, [1939.] 256p.
An enterprising family turns misfortune into personal gain in this novel of farm life on the Illinois prairie during the 1930s. Determined that her family will earn its own way while her husband is in a tuberculosis sanitarium, Lucille Easterly moves with her four children to the abandoned family farm near Kankakee so that their expensive city home can be rented. As she and the children learn the rudiments of farming by the trial and error method, Ellen, the eldest daughter is falling in love, John is deciding on his future vocation, and the twins are experiencing an entirely new way of life and enjoying themselves immensely. The story is too idyllic and the characters too sweet by today's standards, but the novel offers considerable insight into 1930s farm life as experienced and viewed by the urbanite.
The K-House Mystery, by Grace Trobaugh Hay. [New York.] David McKay Company, Inc., [1958.]156p.
The Easterly family, introduced by the author in her earlier novel, Seven Go to Eastcroft, is on the move again this time to DeKalb, Illinois. Hard pressed to find housing in the town, they rent a sprawling mansion, complete with blind stairways, hidden passages, and perhaps a ghost. Although the DeKalb and northern Illinois area background is well defined, the characters seem one-dimensional and the strained plot is highly unlikely.

I do believe it is time for me to see reread The K-House Mystery to see what interested me so long ago.
