I equate to Stranger Danger. Oprah made a big deal out of it-pointing out that most children didn’t know what “stranger” meant and thought a stranger was some evil looking monster. She launched a series of shows on how to explain to your child what a stranger was.
Same with Rapists. Most aren’t some goon lurking in the shadows of a parking lot. They are people we know and often trust. Many don’t think they are rapists. Just drunk and lucky.
