#MeToo.

With these two simple words, thousands of women – and men – are uniting to highlight just how widespread sexual harassment and assault are.

On Sunday night, Charmed actress, Alyssa Milano called for women from all walks of life to stand in solidarity in response to the barrage of actresses and women in media coming forward with their stories of sexual harassment, assault, and even rape at the hands of disgraced Hollywood producer, Harvey Weinstein.

“If you’ve been sexually harassed or assaulted write ‘me too’ as a reply to this tweet,” the 44-year-old posted to Twitter.

Since the tweet was posted, tens of thousands have replied to Milano’s call alone, with many more sharing their stories in individual posts.

Among these are celebrities including Lady Gaga, Gabrielle Union, Sheryl Crow, Sarah Hyland, Busy Philipps, Viola Davis, Barry Crimmins, Anna Paquin, Patricia Arquette, Debra Messing, Rosario Dawson and Evan Rachel Wood.

Me too. Suggested by a friend: “If all the women who have been sexually harassed or assaulted wrote “Me too” as a status, we might give people a sense of the magnitude of the problem.”

Because I was shamed and considered a “party girl” I felt I deserved it. I shouldnt have been there, I shouldn’t have been “bad” #metoo
