Speaking at Johns Hopkins, Elizabeth Smart expressly linked not trying to flee her kidnapper/rapist with abstinence-only education, saying that once she'd been raped she felt worthless:

“I thought, ‘Oh, my gosh, I’m that chewed up piece of gum, nobody re-chews a piece of gum, you throw it away.’ And that’s how easy it is to feel like you no longer have worth, you no longer have value,” Smart said. “Why would it even be worth screaming out? Why would it even make a difference if you are rescued? Your life still has no value.”

These are the exact kind of links we're always making in these stories when people ask "What's the big deal?", but it's absolutely heartbreaking to see it bear out in real life.
