Can you imagine the 2020 version of this scene? Uhura giving Jefferson Davis Trump a round-house kick to the face (yum yum!)
The 60s seemed to be the sweet spot for humanist liberalism.
Eh. I love Classic Star Trek a lot. It is probably my favorite Trek since I have such a fondness for old timey 60's and 70's episodic story telling. It's basically Bonanza in space. But the show could be INCREDIBLY sexist, and I'm not just talking about the short skits and green skinned babes. Gene Roddenberry wasn't racist. But he was, probably unconsciously, sexist as fuck.
Sexism doesn't come from having some sexy characters or fanservice, or having a couple stories where women are simply romantic objects. It comes from a pervasive theme across most episodes that the female characters are either dangerous monster temptresses or innocent, naive, emotion driven, and in need of constant guidance or protection in order to prevent them from letting Hitler or Apollo win. Not every woman is presented this way. But most single episode female character is one or the other or both. If these tropes were used a couple times in the whole show, it wouldn't stand out so much. But it's all the time.
It comes from episodes like 'The Conscience of the King' where Kirk has an weird conversation with the crazy girl Lenore that implies that men are the ones who captain starships and hold power and women can only gain a sliver of that power by seducing them.
And of course the most sexist of all Star Trek episodes 'Turnabout Intruder.' Where a woman body switches with Kirk because she wants to be a starship captain and blames sexism on her being unable to achieve it. But she's irrational and emotionally unstable, unable to handle command. She ends up dying, and the literal last lines of Star Trek are Kirk musing, "
Her life could have been as rich as any woman's. If only... if only..." Implying that if she had accepted the 'limitations' of her femaleness she could have been as happy as a woman could be.
If you wanted to fanwank Turnabout Intruder, you could pretend that the show was saying she was unfit for command apart from her gender and was blaming sexism for her being held back, but the episode, and the whole show, doesn't do a good job of framing things that way.
I'm as sick of SJW libtarded asexual characterless STRONK WAHMAN as much as the next sane person, but I certainly don't want to go back to the days before you could have a T2 Sarah Conner or Ellen Ripley.
