(Society for Cutting Up Men)
by Valerie Solanas
Life in this society being, at best, an utter bore and no aspect of society being at all relevant to women, there remains to civic-minded, responsible, thrill-seeking females only to overthrow the government, eliminate the money system, institute complete automation and destroy the male sex.
It is now technically feasible to reproduce without the aid of males (or, for that matter, females) and to produce only females. We must begin immediately to do so. Retaining the mail has not even the dubious purpose of reproduction. The male is a biological accident: the Y (male) gene is an incomplete X (female) gene, that is, it has an incomplete set of chromosomes. In other words, the male is an incomplete female, a walking abortion, aborted at the gene stage. To be male is to be deficient, emotionally limited; maleness is a deficiency disease and males are emotional cripples.
The male is completely egocentric, trapped inside himself, incapable of empathizing or identifying with others, or love, friendship, affection of tenderness. He is a completely isolated unit, incapable of rapport with anyone. His responses are entirely visceral, not cerebral; his intelligence is a mere tool in the services of his drives and needs; he is incapable of mental passion, mental interaction; he can't relate to anything other than his own physical sensations. He is a half-dead, unresponsive lump, incapable of giving or receiving pleasure or happiness; consequently, he is at best an utter bore, an inoffensive blob, since only those capable of absorption in others can be charming. He is trapped in a twilight zone halfway between humans and apes, and is far worse off than the apes because, unlike the apes, he is capable of a large array of negative feelings -- hate, jealousy, contempt, disgust, guilt, shame, doubt -- and moreover, he is aware of what he is and what he isn't.
Although completely physical, the male is unfit even for stud service. Even assuming mechanical proficiency, which few men have, he is, first of all, incapable of zestfully, lustfully, tearing off a piece, but instead is eaten up with guilt, shame, fear and insecurity, feelings rooted in male nature, which the most enlightened training can only minimize; second, the physical feeling he attains is next to nothing; and third, he is not empathizing with his partner, but is obsessed with how he's doing, turning in an A performance, doing a good plumbing job. To call a man an animal is to flatter him; he's a machine, a walking dildo. It's often said that men use women. Use them for what? Surely not pleasure.
Eaten up with guilt, shame, fears and insecurities and obtaining, if he's lucky, a barely perceptible physical feeling, the male is, nonetheless, obsessed with screwing; he'll swim through a river of snot, wade nostril-deep through a mile of vomit, if he thinks there'll be a friendly pussy awaiting him. He'll screw a woman he despises, any snaggle-toothed hag, and furthermore, pay for the opportunity. Why? Relieving physical tension isn't the answer, as masturbation suffices for that. It's not ego satisfaction; that doesn't explain screwing corpses and babies.
Completely egocentric, unable to relate, empathize or identify, and filled with a vast, pervasive, diffuse sexuality, the male is pyschically passive. He hates his passivity, so he projects it onto women, defines the make as active, then sets out to prove that he is (`prove that he is a Man'). His main means of attempting to prove it is screwing (Big Man with a Big Dick tearing off a Big Piece). Since he's attempting to prove an error, he must `prove' it again and again. Screwing, then, is a desperate compulsive, attempt to prove he's not passive, not a woman; but he is passive and does want to be a woman.
Being an incomplete female, the male spends his life attempting to complete himself, to become female. He attempts to do this by constantly seeking out, fraternizing with and trying to live through an fuse with the female, and by claiming as his own all female characteristics -- emotional strength and independence, forcefulness, dynamism, decisiveness, coolness, objectivity, assertiveness, courage, integrity, vitality, intensity, depth of character, grooviness, etc -- and projecting onto women all male traits -- vanity, frivolity, triviality, weakness, etc. It should be said, though, that the male has one glaring area of superiority over the female -- public relations. (He has done a brilliant job of convincing millions of women that men are women and women are men). The male claim that females find fulfillment through motherhood and sexuality reflects what males think they'd find fulfilling if they were female.
Women, in other words, don't have penis envy; men have pussy envy. When the male accepts his passivity, defines himself as a woman (males as well as females thing men are women and women are men), and becomes a transvestite he loses his desire to screw (or to do anything else, for that matter; he fulfills himself as a drag queen) and gets his dick chopped off. He then achieves a continuous diffuse sexual feeling from `being a woman'. Screwing is, for a man, a defense against his desire to be female.
