Glenn can be very funny.
He’s wrong with his interpretation of the Wizard of Oz, in my opinion.
Glinda symbolizes the Guardian angel and cannot fix Dorothy’s problems for her. Dorothy has to practice virtue herself, in order to learn it, like every other coming of age kid.
Glinda tells the Witch of the West (Evil) that she has no power in her territory. Dorothy had to defeat Evil in her own territory. She’d already killed the Witch of the East (Evil; most likely Miss Gulch) in her desire to go home. So she was up to the task.
Glenn’s not in Kansas anymore.
It’s more like “Wicked” than “The Wizard of Oz.”
