I don't think we get the degree to which technological mediums like Snapchat and Instagram are also changing our relationships. I think we will learn down the line that they have created profound changes in our social and sexual lives.

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.

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.

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.

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.

A refusal of shame about sexual assault and the prioritization of speaking your mind while using your real name - instead of a pseudonym given to you by a journalist. Those ideas were soon taken up by Lena Dunham, Lady Gaga, and Kesha. And now, with Harvey Weinstein's unmasking, they've spread to the top of Hollywood.
