I think that a certain set of fans go, "Hey, the women are doing more than Lt. Uhura, what a wonderfully feminist world!" and never look past that. There's also such a significant amount of confusion in SF fandom between the problematics of a fictional world and the problematics of the depiction of that fictional world. I'm not convinced that BSG's setting is anti-feminist, but I'm absolutely sure that BSG is anti-feminist. Many fandom folks seem to think that the former somehow cancels out the latter, when they're rather unrelated.
