Introducing the Q&A, Watson said: "Thank you so much for all of your support and participation so far. It's been absolutely amazing."
"This is the first campaign of its kind at the UN: we want to try and galvanize as many men and boys as possible to be advocates for gender equality. And we don't just want to talk about it, but make sure it is tangible," Watson said in her impassioned launch speech at the World Economic Forum.
"I was appointed six months ago and the more I have spoken about feminism the more I have realized that fighting for women's rights has too often become synonymous with man-hating.
"If there is one thing I know for certain, it is that this has to stop. For the record, feminism by definition is: 'The belief that men and women should have equal rights and opportunities. It is the theory of the political, economic and social equality of the sexes.'"
