Re: No female starship captains in the 2250s-60s?
I don't agree the intent of the episode is to establish women cannot command. Particularly when the prime example used is a nutbar. And then they don't come out and explicitly say it. What I see is individuals using the words of an obviously irrational character to prove something that isn't supported anywhere else in the series. They are choosing to interpret something in a particular negative way rather than accepting what is a much more likely explanation.
Lester was nuts. Period. Nothing she says can be trusted because she's long lost grip with all reality.
This does not describe my position, and I've already explained why.
