In a 2018 New York Times op-ed Mayim caused offence by suggesting that Harvey Weinstein’s victims invited sexual assault by dressing inappropriately. She reasoned that she had avoided being assaulted or targeted by predators herself because she dressed modestly and did not “act flirtatiously with men.”

She wrote: “In a perfect world, women should be free to act however they want. But our world isn’t perfect. Nothing - absolutely nothing - excuses men for assaulting or abusing women. But we can’t be naïve about the culture we live in." After initially claiming her comments had just been taking out of context she went on to apologize to victims of sexual assault saying: “You are never responsible for being assaulted… I am truly sorry for causing so much pain, and I hope you can all forgive me.”
