Well, I'd say that BSG is feminist from the point of view of first-wave feminism: Women have the vote, and can be found in many positions (including the presidency) that used to be reserved for men.

From the point of view of second-wave feminism, on the other hand, the show looks pretty retrograde. Remember the abortion episode, where the female president is willing to toss away the reproductive freedom of the fleet's women?

I can't really disentangle myself enough from my male and middle-class privilege so as to have an opinion about whether the show is feminist from the perspective of third-wave feminism.
