Andrea Dworkin book Intercourse
This it does with some consistency and some confidence. Violation is a synonym for intercourse. At the same time, the penetration is taken to be a use, not an abuse; a normal use; it is appropriate to enter her, to push into ("violate") the boundaries of her body. She is human, of course, but by a standard that does not include physical privacy.
