Today, we're launching a campaign called, HeForShe

I'm reaching out to you because we need your help

We want to end gender inequality

And to do this,

we need everyone involved

This is the first campaign of its kind at the UN

We want to try to galvanize as many men and boys as possible to be advocates for change

and we don't just want to talk about it

We want to try and make sure that it's tangible

I was appointed as Goodwill Ambassador for U.N. Women six months ago

and the more I've 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
