It's catchy, but . . . I'm not sure that it will really get the message across to the men who rape, particularly those who convince themselves that what they are doing isn't rape.
Some only associate the word "rape" with what Todd Akin referred to as "legitimate rape" - i.e. rape that follows the classic silent film script of deranged strange man violently attacking a chaste woman by surprise and forcing sex. Everything else is something "lesser." If they know each other, they don't believe it's even in the same ballpark as "real rape."
Some simply don't believe they need explicit consent to have sex. Like the George Galloways of the world, they believe that consent once means consent in perpetuity. There's no guess work involved.
Some believe that women are in a perpetual state of consent unless fully and clearly proved otherwise. The bar of proof tends to be pretty high. They aren't guessing about consent. They are assuming it's there.
Some are revisionists. They will insist that both they and the other person were too drunk/drugged to really think about what they were doing. It was just "regretful sex" for both of them, nothing like rape.
In my view, there are many, many men for whom gaining full, enthusiastic consent before having sex isn't really on the radar. I don't think they actually experience ethical dilemmas over whether the other person agrees to sex or to a particular sex act or not. I think we may hope that if men are only told how and why this is wrong, it will twig their consciences and they will change. I'm not really convinced though that will happen.
And the reason for that is that there are so many counter messages out there, telling men that they are entitled to sex with women, any women, wherever, whenever and however they want. If they have to lie to get it, it's okay. If they have to find someone who may be unable to fully consent, it's okay. If they have to bully someone into it, it's okay. So long as they don't step over into anything that could be described as "legitimate rape" by the Todd Akins of the world, it's probably okay. The risk of being held accountable is miniscule. Go fill your boots. It's your right!
Having said that, I do believe that ANYTHING that generates discussion about the issue has the potential to shift these attitudes, to break the conditioning, even where the denial, the outrage, etc. can be soul-destroying.
Sorry if that sounds rather negative.
