Slash fic as it originated in modern fan culture was Kirk/Spock and spread through zines written by women in the 60s.

Also I’ve been watching TNG for the first time lately (late to trek) and I honestly don’t understand how conservatives could really enjoy the best episodes. Like I watched The Drumhead (s4e21) last night and it was aggressively unsubtlely anti conservative. Like honestly I regret not keeping notes from the start of this watch through to have good episodes to recommend to people. First Contact (s4e14) had the villain literally be a conservative trying to preserve his society’s way of life against the progress it would have to deal with if it encountered aliens.
