I don't know why books like this were ever published. They are offensive and just plain cruel. If someone wants to make a point do it without involving innocent children.
This is how Christians think about the mentally challenged? WTF? Using the horrible title as keyword, real life real Christians teachers were instructed to use this book as a reference. Jesus fucking Christ.
This was published in 1969. Not cool, not even then.
Eh.... NehI'm sorry but I think not.
