Don't get too drunk at a party. Don't walk home alone. Don't leave home without your date rape nail polish. Men, when they are addressed, are generally urged to "intervene" in sticky situations (at least until the nail polish dries). In this system, the blame for rape indirectly falls on the careless victim rather than on the abuser.
