Once Donald Trump announced that Betsy DeVos was going to be his Education Secretary - a few months before I finished the manuscript - I had a pretty good idea of what was going to happen. He was going to overturn as much of what Barack Obama did, and the attendant social progress, as he could.

After studying dozens of sexual assault cases, it is clear to me that the "he said/she said" aspect is a big part of what makes them fraught. Many experts agree with this. But that same fraught nature is reflected in both legal standards of consent and philosophical theories of consent.

As Americans, we do love punishment.

If we agree that universities need to monitor sexual violence in various locations, and that they will require students to hew to a narrower set of rules than the wider world, how do we deal with putting these ideas into the brains of teenagers who have been schooled in the disgusting gender norms of our American culture for the previous eighteen years? This is the essential conundrum. Can we teach these relatively young dogs new tricks? I believe that we can.

An interesting reversal is happening right now. The college women who kicked all this off have been superseded in the mainstream media by celebrities like Gwyneth Paltrow and Angelina Jolie. And now a new group of college women - the ones in college now - are looking at Paltrow and Jolie as models for the appropriate way of dealing with sexual predators.

I'm a staunch believer in the effect of pop culture - including advertising and the internet - on the young. Pop culture in its narrowest sense - mass-produced film, TV, and music - either truly reflects what's up in youth culture, or it reflects what youth-filled focus groups have told marketing companies that they want to consume.

I also believe that upending ingrained ideas about what assault is a gun to the head, a stranger, a parking lot and what consent looks like a woman who gives a no really means yes is very messy. And part of the messiness is some students - and yes, usually these are liberal students - over-determining the definition of assault.
