I don't see active fights over the gender war happening in those fronts. It's certainly true that those aren't territories that we control firmly, but it's also not territory that we're disputing very hard. Gender is what it is in the Bible Belt, and most of the pushback is from a younger generation who grew up on the Internet. Gender is what it is in film, but the Bechdel test entered popular consciousness on the Internet. Gender is what it is in the minds of the old advertising firms, but the new ones are often technology companies, their clients are often technology companies, and when you say "Super Bowl ads" and "what they think of women" I can't help but think "GoDaddy". Gender is what it is in the minds of the current elected officials, but Obama's election has been credited, in part, to his ability to use technology more effectively than his opponents (and, therefore, to effective technologists wanting to work for him). Silicon Valley is the trench and the fortification; if it falls, we can then march on the cities.

Now, of course, there's a question as to whether the gender biases of the makers of the Internet impact the gender biases of the things that happen on the Internet. But I think they do. At the least, for fora like Reddit and HN where the platform and editorial direction are linked, it seems obvious that they must. For platforms like Twitter or G+, policies such as harassment response and tradeoffs, whether real names are common or uncommon[0], what speech is considered appropriate or inappropriate, etc. can all impact what voices are heard and who is empowered by the platform.

[0] I don't mean by this to imply that there's a standard feminist answer on whether real-name policies are good or not. There are feminist arguments on both sides.
