And yet, women characters are constantly depicted in sexualized, objectified manners (Troi's costumes especially), and the two main female characters are depicted in traditionally female-gendered caregiver roles. Troi is often depicted as uncertain and questionably competent in command scenarios. Women characters like Troi and Luxana are depicted in ways that fulfill stereotypes of women (loving chocolate, being overbearing and controlling of children, being hedonistic). Ambitious or assertive women characters like Shelby or Nechayev are depicted in harsh, critical terms. Women characters like the title character of "The Perfect Mate" are literally depicted as beings that exist to fulfill men's desires, and it's depicted as a tragedy that Picard cannot possess her instead of it being a tragedy that she's not given agency over her own life. When Lal is created, she is told that she "must" assume a gender role, and then, after she assumes a female gender role and kisses Riker, Data asks Riker what his "intentions" are as though he has some sort of ownership of his daughter in a patriarchal society. When Leah Brahams sees that Geordi has cyberstalked her and created a holographic re-creation of her, she is depicted as being unreasonable and mean-spirited for reacting with anger to his creepy, possessive, boundary-crossing, and stalking behavior.
Sorry, but it's perfectly fair to complain that TNG is sexist even if the characters imagine in-universe that their society is egalitarian.
