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.

As Americans, we do love punishment.

As a journalist, I try to be as fact-based and objective as possible, though I'm also aware that objectivity is an illusion. This way of moving through the world is what separates journalists from activists.

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.
