Context: But the hatred of women is a source of sexual pleasure for men in its own right. Intercourse appears to be the expression of that contempt in pure form, in the form of a sexed hierarchy; it requires no passion or heart because it is power without invention articulating the arrogance of those who do the fucking. Intercourse is the pure, sterile, formal expression of men's contempt for women; but that contempt can turn gothic and express itself in many sexual and sadistic practices that eschew intercourse per se.

Context: To call woman the weaker sex is a libel; it is man's injustice to woman. If by strength is meant brute strength, then, indeed, is woman less brute than man.

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.
