....except for the very awkward essay by Kirk in one of the movie novelizations where he addresses the Spock rumor - which as a kid was the first time I'd encountered the idea of same sex relationships treated with something like equality.
Really? Which novelization was that? I don't remember and I haven't read any of the TOS Movie era novelizations in awhile...
It's a footnote from Roddenberry's ST:TMP novelization, which was presented with the conceit of being a dramatization of actual events with an introduction and occasional commentary by Admiral Kirk. The footnote is from p. 22 of the scene where Spock is about to accept the Kolinahr medallion and renounce his former life forever, and thinks a farewell to Kirk, his t'hy'la The footnote reads:
Editor's note: The human concept of friend is most nearly duplicated in Vulcan thought by the term t'hy'la, which can also mean brother and lover. Spock's recollection (from which this chapter has drawn) is that it was a most difficult moment for him since he did indeed consider Kirk to have become his brother. However, because t'hy'la can be used to mean lover, and since Kirk's and Spock's friendship was unusually close, this has led to some speculation over whether they had actually indeed become lovers. At our request, Admiral Kirk supplied the following comment on this subject:
"I was never aware of this lovers rumor, although I have been told that Spock encountered it several times. Apparently he had always dismissed it with his characteristic lifting of his right eyebrow which usually connoted some combination of surprise, disbelief, and/or annoyance. As for myself, although I have no moral or other objections to physical love in any of its many Earthly, alien, and mixed forms, I have always found my best gratification in that creature woman. Also, I would dislike being thought of as so foolish that I would select a love partner who came into sexual heat only once every seven years."
(Gee, I wonder how Dr. Chapel felt when she read that last sentence...)
I agree, that was a pretty significant statement at the time, Kirk expressing the attitude that there was nothing wrong with alternative sexualities, even if he personally wasn't into them. Although it's interesting to note that he says women provide his best gratification, not his only gratification.
