"The current president is a woman; the president who was killed in the initial attack, whom she succeeded, was a man. We see two admirals and two top gun pilots, in both cases one is male and one is female. Women are strong and powerful, and better yet, no one questions it. There are lots of reasons that characters question each other’s authority, judgement, morals, and even humanity, but gender never factors into it. This is a positive model for viewers of how women should be treated in society. Additionally, there are a lot of heterosexual couples, and in almost every instance the wife and husband are equal partners. Some marriages are tumultuous, but the men do not dominate the women."
