Jenny, even if we're sober, we expose ourselves to predators every time we leave the house. Rapists strike at bars, dark unlit parking lots, in the park, even in our own homes. Look at the women who get attacked as they're walking to their car at night in an empty lot, or even just jogging in the park. Or even at home, and someone breaks in. Look at all the women and kids who get snatched off the streets everyday, and end up raped and murdered.
You don't gotta be drunk to have an encounter with a predator.
