I’ve had my attention drawn to the Anomaly podcast about hermeneutics and Star Trek. It emphasizes why “It was the 60s” is not a sufficient justification for things like sexism on Star Trek: The Original Series. Here’s a sample:
I tend to think there’s also extra pressure on Star Trek because it has a reputation for being progressive. For the time it was made it, it often was. But not always. And it’s worth noting that, in Letters to Star Trek (compiled by Susan Sackett), you can find several instances of women fans writing in and objecting to the portrayal of women of TOS. In the ’60s. (Some examples can be found here.) So, saying “it was the 60s” obscures and dismisses that history.
