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.

I finally stopped fretting and tried to think of Donald Trump's election as an opportunity. I didn't shift my thesis but I added some lines, in the Blurred Lines introduction, to my description of the progressive awakening that has happened in this country over the last five years - "Trump's presidency is a macroaggression". I wanted Trump to be a specter from the book's outset.

Colleges are a unique space in our culture. They're a temporary constellation of humans, like a workplace. And the rules about sexual assault and harassment in a workplace are narrow rules. They're stricter than what's considered criminal on a city street. By this logic, the same rules should exist at universities too.

We need new cultural scripts. Women don't say what we want, and we don't say what we don't want. Unless we're reacting to a stranger, we generally aren't great at turning down someone's advance.

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.

Harvey Weinstein is a monster. And what campus victims are talking about has a lot more gray in it - many more complexities.
