Equality is not a concept. It's not something we should be striving for. It's a necessity. Equality is like gravity. We need it to stand on this earth as men and women, and the misogyny that is in every culture is not a true part of the human condition. It is life out of balance, and that imbalance is sucking something out of the soul of every man and woman who's confronted with it. We need equality. Kinda now.
At the end of the day I have many answers for it. It has to do with my mom, who was an extraordinary woman, and a great feminist. It has to do with the people in my life. It has to do with a lot of different things, but -- I don't know! Because I'm not just writing from the female characters for other people. I have a desire to see them in our culture -- that was not met for most of my childhood. Except occasionally by James Cameron. [From the 2011 San Diego Comic Con, in response to being asked why he writes strong female characters.]
