" What happens to that industry—and to the shrill threats of moralists—when a female conceives only as an act of volition, when she is immune to disease, cares only for the approval of her own sort . . . and has her orientation so changed that she desires intercourse with a whole-heartedness that Cleopatra never dreamed of—but any male who tried to rape her would die so quickly, if she so grokked, that he wouldn’t know what hit him? When women are free of guilt and fear—but invulnerable? Hell, the pharmaceutical industry will be a minor casualty—what other industries, laws, institutions, attitudes, prejudices, and nonsense must give way? "
