Actress Rosario Dawson has shared her story as a survivor of child sexual abuse.

In an interview with the Morado Lens podcast in the US, the Rent and Marvel series star discussed her support for the #MeToo and Time's Up movements and the campaign against sexual abuse, assault and harassment in the workplace.

"These things are just sort of insidious kind of, 'This is just the way that it is'," she told hosts Cindy Rodriguez and Nathalie Farfan.

"And then we don't really question it and then we don't recognise how many other places it shows up in our lives, where we discount ourselves or we don't speak up for ourselves or for each other."

"The interesting thing, I find, especially in all this big sexual harassment stuff, is all the people who were also complicit like, 'I knew he was bad, but I didn't say anything'," she continued.

"For me, it's like, I grew up and I was raped and molested as a child, so for me, the world was like that since I was a child," said Dawson.

"So when I saw it in the workplace, it wasn't foreign to me. It was like, 'Well, that even happens within family. It happens with people that are supposed to take care of you when you're a child'."

Dawson said "a major reckoning" and "cultural shift" was now taking place.

"I have over many years [raised issues] but I never really made it personal because so often it wasn't about me it was more about, 'Let's look at this insidious problem that we have everywhere', but also recognising that again it would potentially probably have to continue to be compartmentalised because there's certain ways that this industry and all these different industries keep pushing that agenda."

"But now we're in a place where it's finally, like, 'No. We don't have to keep passing this on'," she said.

"This is archaic and terrible and destructive and let's look at it. And it's beautiful. I'm so ready for this moment."
