Point of Order: Uhura WAS supposed to be in charge of the Enterprise at one point in the original series. It was Executive Meddling
, not a lack of progressiveness on Roddenberry and Co.'s part, that kept Uhura out of the captain's chair.To wit:
"Uhura, the most visible female character, was denied a chance to command the Enterprise in one episode because an executive flat out told Roddenberry 'we don't believe her in charge of anything'. Nichelle Nichols got a lot of crap thrown her way by the executives for reasons that today are obviously both racist and sexist; for the first season, she wasn't a regular member of the cast, and her fan mail was kept from her. She almost left the show, until she met Martin Luther King Jr. at a party, who convinced her to stay on and serve as a black role model."
