Allison Williams has questioned whether sexual assault is due to the way boys are raised.
The Girls actress and fellow cast members Lena Dunham, Jemima Kirke and Zosia Mamet have appeared in a public service announcement (PSA) urging society to make it easier for sexual assault victims to come forward.
The issue of how American society - and the legal system - treats victims of sexual assault was brought to the forefront recently when Brock Allen Turner received a six-month prison sentence for sexually assaulting an unconscious woman when he was at Stanford University.
Allison, 28, made her controversial comments in a new interview where she shared her very candid thoughts on the prevalence of sexual assault.
"There are so many things involved: it's the bystanders, it's boys not knowing that they need consent, it's also drinking culture - but to blame all of those things and not say that maybe there's an issue with the way we're raising our boys," she told Marie Claire's U.S. website.
Allison explained the aim of the PSA, which they had started work on before the Stanford rape victim's statement was released, was to spark a national conversation about the issue of sexual assault. However, she conceded it was hard to pinpoint just one reason why the issue is so difficult to discuss.
"The whole message of our PSA is this is a personal relationship you might have with this event. It could be someone you know and love. You don't even need to worry about any of the politics, you just need to listen, and be there for her or him," she stressed. "My hope was that the PSA would spark people into thinking about sexual assault, and at the very least mean that survivors felt seen."
