What is #MeToo and why it's the most important thing you'll see in your newsfeed today.

#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.

Whether you’re reading it, scrolling past it, tweeting it, or perhaps, the reason someone else is, the message is clear:

You are not alone. And this will no longer be tolerated.
