Statistically, most murderers are not rapists and most rapists are not murderers. Also statistically, defending yourself works. Predators are looking for prey, not combat. In most cases, an aggressive, confidant posture and brandishing a weapon will be enough to give you an opportunity to escape.
I tell my wife to be smart. Follow her instincts and avoid dangerous situations. But if someone tries to violate her body, to fight back with everything she is.
Pay attention. Make good decisions and keep your head on a swivel. Do everything you can ahead of time to protect yourself from violence. But if you get attacked, bite, claw, scream and struggle until either you escape, or one of you is dead.
That may not be the decision everyone makes, but it's what we teach in the Sandwell home.
