I have no idea. I've never argued that. My point has always been that we've never bothered to do unbiased research. Essentially, the people who wrote our first rape laws were living with the stereotype that men are always sexual aggressors and women are always sexually passive. So the language of the law made it clear that it was only a crime for a man to force a woman to have sex, not vice versa. Because people couldn't even conceive of the reverse happening. So this took a stereotype and legitimized it by building a law on top of it. Then in the 60s, we started paying more serious attention to the scope of rape. And while that was a good idea, researchers ended up reinforcing stereotypical views by only asking women about victimization and only asking men about perpetration. So the stereotype is now reinforced twice, by law and science. The idea is normalized that it's only rape when a man does it, further blinding people to asking whether the reverse ever happens.
Now cut to a few years ago. The CDC did a massive survey called the National Intimate Partner Sexual Violence Survey. Their results showed a vast difference between the numbers of female and male rape victims. Yet, when someone looked at their data, they realized that they actually had asked men about victimization by women, but they deliberately did not classify this as rape. They called it "forced to penetrate". And the numbers showed that, for the previous 12 months, 1,270,000 women reported having been raped, and 1,267,000 men reported being "forced to penetrate". 98% of women reported their attacker was male, 80% of men reported their attacker as female. So these numbers don't prove anything in and of themselves. But they absolutely suggest that, if we were actually doing research unblinded by stereotypes, our perception of rape would likely be a hell of a lot different than it is now.
