Ignorance: Watered Down Fairy Tales:

The original story "Aladdin and the Wonderful Lamp" from "Tales of 1001 Arabian Nights" begins, "Aladdin was a little Chinese boy."  In the original "Little Red Riding Hood", the wolf kills Grandmother and serves her to Red before swallowing her, the man gutting him to save her, but it was too late for Granny, and two animals spoke and quite profanely told Red so, though she didn't understand.  Rapunzel's prince lost his eyesight until her tears cured him.  These and many other stories have been around for centuries, and many people have seen the more recent trend of taking fairy tales and making the grittier, more intended for adults than children, denouncing it as perverse and ruining their childhood.  Originally these stories had many details quite different from how most know them today, usually dark and considered too disturbing to be a bedtime story.  The time they were spread around though, The Black Plague and other dangers were in abundance, and life was generally much harsher, children needing strict reminders to keep them from dying early in life.  These tales were fascinating to the imagination, but more intended for their blunt lessons.  The Brothers Grimm and many others took these stories and many others and softened them even further than the corruption that time had done to them, and even those changes were not final as they were softened even more.  Fairy Tales adapt to society as it changes, and now that we are in a more blunt age again with regard to sexuality, violence and other taboo subjects, the tales are darkening despite some resistance, back toward their initial roots.  It is cyclical and they will likely lighten again, but it is not that someone is altering the original story to make it corrupted; The fairy tales were watered down before and now the concepts that alter it, twist it, and deform it echo back to their more concentrated, original form.
