Emma Watson marked International Women's Day by holding a Q&A session at Facebook's London headquarters to a live audience and a larger online audience, who tuned in to watch the Facebook stream. The actress and United Nations (UN) Ambassador answered questions about the 'HeForShe' campaign for which she has been an inspiring advocate ever since her impassioned speech at the UN last September. 

Her new responsibilities as the face and voice of the campaign haven't come without resistance. She revealed during her talk that ever since her first address last year she has received threats from an anonymous online user, who posted a picture of the actress with the warning 'You're next' next to a countdown clock, and a threat to expose nude pictures of her. She knew it was a hoax and that the pictures didn't exists but she said the threat demonstrated perfectly, the very inequality she is fighting to correct:

"I was raging, it made me so angry, I was like, this is why I have to be doing this. If anything, if they were trying to put me off it, it did the opposite." she said, in her brilliantly determined way.

She summed up why feminism is so important: "Our society in general devalues the 'she' – qualities that are associated with the feminine that are found in all of us. As a result there's this imbalance and this distortion and it's hindering our progress."

So what exactly is feminism? Watson summed it up in a nutshell:

"[Feminism is] equality: politically; culturally; socially; economically. That's it, that simple." 

On why men and women are both part of the problem and the solution, and destigmatising the word 'feminism': "Gender equality, historically has been predominantly a women's movement for women. But I think the impact of gender inequality and how it's affecting men hasn't really been addressed.... Men think it's a women's word. But what it means is that you believe in equality, and if you stand for equality, then you're a feminist. Sorry to tell you. You're a feminist. You're a feminist. That's it."

Watson was asked by a member of the audience if she was paid less than her male counterparts in the Harry Potter films and he humbly replied: "I wouldn't dream of complaining about my financial circumstances, but yes, it is a big problem in my industry, it is a huge problem that needs to be addressed."

And we will leave you with this truly brilliant analogy about why men and women need to work together: "The human race is like a bird and it needs both wings to be able to fly. And, at the moment, one of its wings is clipped and we're never going to be able to fly as high."
