The idea that our women's brains can't tell if we've been assaulted or just got a little bit too friendly with the new guy in tech support and are ashamed the next day is offensively insulting.
I'm very wary about this kind of statement. People seem to be able to embrace all kinds of concepts if they are told they are the truth.
There have been some interesting journalistic investigations around what young people are taught about sexual assault that suggest that if they are given information that is confusing, they will be confused. You can also see some disturbing numbers around accusations of sexual assault in some universities in the US where there are far more against black men, all out of proportion to their numbers on campus.
We saw some of this come out with Me-Too, where there were several incidents or even literature presented as part of the Me-Too movement that created controversy, and that was really the dividing line - was this bad sex or sexual assault? The article about Aziz Ansari is probably the best example. But even here on MN I've seen people claim that having sex because you are nagged is a sexual assault.
Now, some may respond, yes obviously those things all are sexual assault, but I think the disagreement about that is the point.
As far as the article however I think the author is being naive to think there were no rapes. But it might be the case that there was a different sort of culture generally about expectations around women saying no, I've noticed some change in that direction within my lifetime.
