I’ve always thought the Romulans weren’t just the Vulcans who rejected Surak’s teachings, but also any who didn’t have the physical ability to follow them.

Originally it was just based on Romulans not expressing any psychic abilities, but Picard also established that sharing personal details publicly as a major taboo. That would track with them being a mix of former enemies who are concerned with suppressing the rivalries that lead to nuclear war.

“Spock’s Brain” actually was licensed and performed by a community theater as a comedy. The teaser and part of the first act used to be on YouTube.

I thought that point about the season finale was the whole point of the episode. Pike and his style weren’t right for the situation. He was like a caricature of Picard without the tactical superiority to back it up.

It also might be another reason Enterprise was the ship kept out of the Klingon war.

From what we’ve heard, about the only thing Roddenberry liked about the idea for Captain’s Holiday was that in addition to the heterosexual couples in the background , he could have gay couples. The writer thought it would get the episode dropped, and in Chaos on the Bridge, Berman was very direct about having to stop that in its tracks.

If it was Roddenberry and not his power tripping lawyer or Paramount who killed Blood and Fire, I expect he was being petty about how Gerrold went from adoring him to arguments and mutual disrespect during the calamity that was TNG season 1.

And when Enterprise did that, there were fans who insisted it was a retcon. It’s something people beleived since TOS even though it was contradicted pretty soon after the Federation was even established.

There are several other things that fans have been certain of since the 60s (like saucer separation being irreversible in the field or Vulcans only having sex during Pon Farr) that weren’t the production intention, but this one was blatantly impossible and it’s very strange.

Spock is the first or only Vulcan in Starfleet. The crew of the Intrepid would like a word.

These can be tough, since three generations of fans have worked on later shows or ancillary official materials. E.g. Startrek.com used to say that about Spock.

Lots about Klingon history: they stole warp tech from the hurq, the hurq (who came after Kahless and stole his relics) are the gods of ancient Klingon myth. Klingon warrior culture is a recent aberration (claims one lawyer whose parents were undervalued academics). Kahless lived a thousand years before TNG. That’s only half the time since Surak or Charlemagne, but fans want to see him more like King Arthur or Robin Hood.
