"The Glinda Conspiracy Theory
Thanks to the Internet, over the years many Oz fans have circulated opposing (and, of course, usually tongue-in-cheek) theories suggesting that Glinda the Good Witch might actually be the true villain of Oz. Some have pointed to the fact that Glinda gloats a bit too morbidly over the death of the Wicked Witch of the East, calling for celebrations and then actually taunting the witch’s sister. Then, of course, there’s the simple fact that Glinda, though she knows the ruby slippers will send Dorothy home, hides this fact from Dorothy and sends the unwitting girl off to do her dirty work for her, all so she herself can finally rule over the land of Oz.
