Some years ago, I read an account online of a young woman who said she had been disfellowshipped at age 12. Her story was that she babysat for neighbors, and that the children's father raped her. I'm unclear on most of the details. In a way, this story raises more questions than it answers. There is also the fact that I've forgotten a lot. I do remember that it made me feel sick and horrified.
She said that she reported the rape (to the elders? to her parents?), and a JC was assembled to interrogate her. She was criticized for wearing shorts in the summertime, wearing lipstick, and making herself a temptress of sorts. (Are men so pathetically weak that they can't stop themselves from raping a 12-year-old wearing shorts and lipstick?)
The upshot of it all is that she was DF'd. Maybe she had unbelieving parents. I don't remember anything in the story about whether the rapist was prosecuted or even reported to the police by anyone.
