At the time that Star Trek premiered, the only astronauts for the U S were men. Russia had one woman cosmonaut. That was “then” so Capt. Kirk was right.
But remember that Kirk had two women in his crew, Uhuru and Rand, one Japanese-American, one Scotsman and one Russian.
The show was way ahead of the UN aholes!
“Hogan’s Heroes” had a very diverse cast, but Klink, Schulz and Burkhalter were all Jewish.
Robert Clary’s family was almost all killed by Nazis as I recollect reading.
Roddenberry liked women in short skirts. That’s why the women had outfits like they did. Almost all the women on the show had little to do with equity.
P.S. Nurse Chappel was Roddenberry’s real life wife.
