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.
