I rewatched Profit and Lace a few months ago. It wasn't as bad as I remembered.
It's difficult talking anywhere about differences between men and women. Say there are too many differences you're sexist, say there are none you're ignorant. Say there are average differences between men and women but they don't apply to any given individual man or woman, people get bored and stop listening to you. (See! You're doing it now!)
In farengi society women are literally and legally considered possessions, they have no rights and never have, it makes sense that gender behavior would be more separated in farengi than in humans. The only other farengi woman who ever appeared was just as greedy ad cunning as the farengi men.
But, it also makes sense that in a society where women have no rights, the way to get men on your side is to assuage their fear that making profits won't make them less feminine.
