I can't belive I have never seen that story before, it's just insane.
The last paragraph is my favorate...
"I know what Pazuzu meant about existing inside you," Julie says. "He was my father," Reagan says. "I already knew that, but there's more" says Julie. "Your homosexuality is the result of his perversion. It's in your blood, and it's a sin. As long as you sin, that part of him that's in you makes you vulnerable to him. You're feeding him." Reagan says, "But what about you? You're guilty of the same sin." Julie says, "I was never gay before. I was touched by the shadow within you. You have to reject it, and we have to be what we were: friends." Reagan nods and smiles with tears in her eyes. "The very BEST friends."
So the moral of the story is, don't be gay or the devil will possess your son.
