All wickedness is but little to the wickedness of a woman. ... What else is woman but a foe to friendship, an unescapable punishment, a necessary evil, a natural temptation, a desirable calamity, domestic danger, a delectable detriment, an evil nature, painted with fair colours. ... Women are by nature instruments of Satan -- they are by nature carnal, a structural defect rooted in the original creation.
-- Malleus maleficarum (The Hammer of Witches), published by Catholic inquisition authorities in 1485-86
The Freikorpsmen hate women, specifically women's bodies and sexuality. It would not be going too far to say that their perpetual war was undertaken to escape women; even the motherly battlefront nurse is a threatening intrusion in the unisexual world of war. This hatred -- or dread -- of women cannot be explained with Freud's all-purpose Oedipal triangulation (fear that heterosexual desire will lead to punishment by the father, homosexual yearnings for the father, or some such permutation of the dramatic possibilities). The dread arises in the pre-Oedipal struggle of the fledgling self, before there is even an ego to sort out the objects of desire and the odds of getting them: It is a dread, ultimately, of dissolution -- of being swallowed, engulfed, annihilated. Women's bodies are the holes, swamps, pits of muck that can engulf.
--Barbara Ehrenreich, from the foreword to Klaus Theweleit's Male Fantasies
Western-style misogyny probably has its roots in a Greek/Roman culture that gave women little power, political or otherwise, despite including women in its pantheon of gods. One could also point to the deep psychological roots in the urge to civilize, particularly in the view of nature as wild, harmful, something to be repressed and tamed; as women became identified with nature, the desire to control them took root as well.
But the particular psychological component that creates the twist of murderous misogyny comes from Dark-Age Christianity: the notion of humankind -- and indeed, all of nature --as innately sinful. Because the chief burden for that sin fell on women who already had no power.
