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.

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 The college women who kicked all this off have been superseded in the mainstream media by celebrities like Gwyneth Paltrow and Angelina Jolie.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.

Let's reach the students who will abide by a "yes means yes" standard in sexual behavior and reeducate them to use it. And as more and more of them use it, others will adopt it too. We're on our way to a new social norm and that's a beautiful thing.

It's true that a dangerous combination of certainty and ignorance often shows up around sex and consent on campus. People on all sides of the issue have such strong feelings about it that they're blinded to the facts.

I make a strong case for poor sexual communication as the root cause of some assaults. I say some assaults because we know, as well, that there are dyed-in-wool, compulsive predators like Harvey Weinstein on campuses too. But there are guys we can reach here. Once again, I'd like to be optimistic in the way that we look at this problem.

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.

Regarding punishment, we've learned from the downfall of Harvey Weinstein and other famous men not only that times have changed, but also that ostracism is an efficient tool. It reminds me of the tradition of bathroom lists of sexual assaulters at Brown beginning in 1990. Back then the administrators called the students who wrote them "magic marker terrorists" and threatened them with expulsion if caught. Now a Shitty Media Men list can dominate the news for days as HR departments across the coasts hastily assess their employees and their liability.
