Ah. So that's why Pike said, "It's just that I can't get used to having a woman on the bridge." Makes sense.The indications are from the beginning ("The Cage") that women were supposed to be on equal footing with men. The intent if not the full-fledged execution was there.
No, wait, it doesn't. Actually, it sounds like things are in the process of changing, and that women are just at that point getting promoted to senior officer positions. That actually dovetails perfectly with Roddenberry's vision of no female starship captains in "Turnabout Intruder." With only twelve starships, at least for the sake of argument assuming that in this case "starship" means "like the Enterprise," and with women only recently in senior officer positions, relatively speaking, it would actually make sense and not be unexpected, if there were still none in those 12 highly-prized positions, even fifteen years later.
In fact, maybe TI was simply referring to just the 12 (what we now call) Constitution-class starships, and maybe promotion was actually merit-based, but women with qualifications hadn't filtered up through the ranks to those few prestigious posts, because they had previously been discriminated against up until sometime just before the events of "The Cage."
Take Roddenberry's anecdotes for what they're worth, but he claimed that he originally proposed the crew be half female, but the network objected because, "Don't you see? It's going to look like there's a lot of fooling around going on up there!" so he reduced it to one-third.
If that could be corroborated, it would be most interesting indeed. Unfortunately, GR has quite a history of self-serving myth-making and blaming the network, and other people in general, for things that they simply didn't do.Roddenberry once stated that the initial ratio of the Crew was 50/50 and the network made him change it because it implied the unmarried crew would be pairing up. Then Roddenberry stated that if you applied the same logic to the resulting 1/3, 2/3 ratio implied the women would be sleeping with more than one man.
Was any of that about the network true? We may never know.
