I'm reposting here what appears to be a condensed version of another brilliant article on the subject (can't find the entire article online) by Thomas Macauley Millar -
I think the key to changing the rape culture is to change the view of sexuality from a commodity model to a performance model.
What I mean by a commodity model is the view that sex is something women have and men get; what Amanda Marcotte refers to as the "pussy oversoul" that women are guardians of and that men make applications for access to. Sex is like a ticket; women have them and men try to get them. Women may give them away or may trade them for something valuable, but it's a transaction in a good.
The commodity model is shared in common by both the libertines and the prudes of a patriarchy. To the libertine, guys want to maximize their take of tickets. The prudes want women to keep the tickets to buy something really important: the spouse; provider, protector, etc.
That whole model is wrong. Under that model, consent is not an affiramtive partnership. Instead, if someone tries to take a ticket and the owner doesn't object, then the ticket is free for the taking. Under this way of thinking, consent is the absence of "no." It is therefore economically rational to someone with this commodity concept of sex that it can be taken; rape is a property crime in that view. In the past, the crime was against the male owner of women (let's not sugar-coat it; until very recently women were in a legal way very much male property and still are in many places and ways). Even among more enlightened folks, if one takes a commodity view of sex, rape is still basically a property crime against the victim.
The better model is the performance model, where sex is a performance, and partnered sex is a collaboration between the partners; like dance or music.
Under a performance model, consent is not the absence of "no." Consent is affirmative participation. Who picks up a guitar and jams with a bassist who just stands there? Who dances with a partner who is just standing there and staring? In the absence of affirmative participation, there is no collaboration; forcing participation by coersion is not a property crime, but a crime of violence like kidnapping.
Under this model, looking for affirmative participation is built into the conception. If our boys learn this from their pre-adolescence, then the idea that consent is affirmative rather than the absence of objection will be ingrained.
The performance model has the added feature that it eliminates slut-baiting. A commodity is finite; if women give or trade away their tickets, they have lost something of value, and the relevant question is what they got in exchange. If sex is a performance, then the question is how well it worked out. There's no finite commodity to run out of, and nobody gets called a slut for jamming with too many musicians.'
