The Women Of 'Girls' On Why We Need To Believe Sexual Assault Survivors

The cast of "Girls" is on a mission to fight rape culture and sexual assault. 

In a video for NowThis News, actresses Lena Dunham, Jemima Kirke, Allison Williams and Zosia Mamet deliver a powerful PSA about sexual assault and victim-blaming.

The women of "Girls" remind those watching that sexual assault is not a crime that's usually committed by strangers lurking in the shadows. Eighty percent of attacks are perpetrated by someone the victim knows.

"This isn’t a secret. It’s reality," the actresses say in unison. "So why is our default reaction as a society is to disbelieve or to silence or to shame?"

Nearly one in five women will be sexually assaulted in her lifetime. "You already have the power to create a safer, healthier environment for women to come forward,” Williams says. 

"Please support, listen, take action," the women say together. "Not because she’s someone’s daughter, or someone’s girlfriend, or someone’s sister, but because she is someone."

Yes, yes, and more yes.
