You're absolutely right Guy.
However I do have to correct something stated falsely by fahl5 - the fact is the Grimms collected both children's and "household" tales, and those were NOT for children originally and were later sanitized in order to present them more widely. But this had led to folktales in general being thought of as children's stories, which is totally false. They were originally just stores of any kind including adult.
The leading scholar Jack Zipes on the Grimms has just published the original edition of the tales. He gave an interview about the changes made to the real stories:
Zipes describes the changes made as “immense”, with around 40 or 50 tales in the first edition deleted or drastically changed by the time the seventh edition was published. “The original edition was not published for children or general readers. Nor were these tales told primarily for children. It was only after the Grimms published two editions primarily for adults that they changed their attitude and decided to produce a shorter edition for middle-class families. This led to Wilhelm’s editing and censoring many of the tales,” he told the Guardian.
Sorry Paul! I don't mean to hijack the thread. I just had to respond to that.
