Trump supporters walked out on Amy Schumer. Then things got interesting.

Thanks to Mr. Trump, we’re really talking about sexual assault.

While giving a performance in Tampa, Florida, comedian Amy Schumer took five minutes to speak harshly about presidential candidate Donald Trump. While the media made a mountain out of a molehill over the 200 Trump-friendly attendees (in a 21,000 seat venue) who left as a result of her political material, there was something even more significant that no one noticed. And it’s something for which we can thank Donald Trump himself.

While the group of Trump supporters left the theater, Schumer did something I’m sure is unprecedented. She brought up the house lights and said:

“If you’re a survivor of any kind of sexual assault, please stand up. You don’t have to. If you feel comfortable enough. If you’ve been sexually assaulted, please stand up … Thank you, ladies, for standing up … And you, sir. You guys … Thank you.”

Women stood. A lot of them. Men stood, too. It doesn’t even matter how many. What matters is that Schumer, who counted herself among them, never would have invited this group to identify themselves in such a massive public space, if it weren’t for Donald Trump.

Thanks to Trump’s behavior, current and caught on tape, we have not only exposed his attitudes and potentially illegal actions, but we’re also talking about this issue in new ways. His behavior, and the public responses to it — positive and negative — have exposed a toxic public norm: that objectification, harassment, and assault of women is acceptable, common, “locker room talk.” Except, of course, it’s not.

By exposing that toxic norm, we finally have a chance to change it, and we are. Athletes like Chris Kluwe, LeBron James, and others are stepping up to say so, along with (certain) politicians, debate moderators, and so many others. Notably, so many other men. Not just men, obviously, but men are speaking out en masse at levels we’ve never seen about sexual harassment and assault. Even louder than we all did about the rape culture swirling around the Brock Turner case. Because, for one thing, Brock Turner wasn’t already a national figure at the time of accusation. Thank you, Mr. Trump.

The experience of sexual harassment and assault is nothing new to women, or men (or, to be sure, people elsewhere on the gender spectrum) all over the world. But a dialogue about acceptable behavior and treatment on such a national level, with male voices speaking just as loudly as women — that is unprecedented. A public invitation to identify oneself as a survivor — in spite of all the reasons survivors are silenced, recently made so clear — is unprecedented.

The norms themselves have not been erased. That will take a lot more work. But now, despite Trump’s apparent traumatic, triggering effect, women are speaking out despite fear of retaliation or of simply not being believed. For many, fear has been replaced by anger — the vocal kind. Men who previously remained silent are calling out Trump and calling for everyone to be better. Trump has started a conversation that can never be taken back. And while it is true that those who will still excuse, deny, and hate are digging in their heels, they are digging their heels at a different place than where we were before the bus video. Thank you, all who are now standing up — at Amy Schumer’s show and so far beyond. And thanks for everything, and nothing, Donald Trump.
