I'm in favour of hipster androgyny: Any trend that permits men to rebel against strict gender rules of appearance is going to make the world a more expressive and sensitive place for all of us.

From its beginning, fan fiction has been written mostly by women. Originally, this was because of a dearth of interesting female characters in conventional sci-fi.

Most critics of gender division are women, and they're worried about girls and the roles presented for them by gendered entertainments. They are quite right to be. Telling girls that the cars and the guns are beyond their domain of expertise, and that they should content themselves with clothes and friendships, is limiting.

My son craves picture books about Transformers and Ninja Turtles and the Hulk; they show one fantastic creature smashing or zapping another into smithereens on page after page. They are dull and ugly and show no interesting stories or models of conflict resolution or character building.
