Trek's problem with sexism is more with the breadth of female characters rather than the individual traits of a particular character or race i.e. certain traditionally 'sexist' portrayals crop up far more often than other types of portrayal. It's a broad problem. Examples of matriarchal societies are often treated with skepticism by our male heroes while those cheeky scamps the Ferengi are just humoured.
The worst example of sexism I have seen recently was in the Planet of the Apes reboot. Female apes are very much a guiding force in ape society but as soon as the apes become more intelligent, the male apes firmly take charge, the men go off to fight, and the women stay at home doing whatever it is that intelligent female apes do. I'm guessing... cook food and tidy up the shacks? We don't really know because they don't really feature any female apes except one who is debilitatingly pregnant, as chimps so frequently are.
