You may want to rewatch Amok Time.
T’Pring’s choice of Stonn is very much emotion based.
SPOCK: Yes. I’ll follow you up in a few minutes. You will instruct Mister Chekov to plot a course for the nearest Starbase where I must surrender myself to the authorities. (the sound of a transporter off screen) T’Pring. Explain.
T’PRING: Specify.
SPOCK: Why the challenge, and why you chose my captain as your champion.
T’PRING: Stonn wanted me, I wanted him.
SPOCK: I see no logic in preferring Stonn over me.
T’PRING: You have become much known among our people, Spock. Almost a legend. And as the years went by, I came to know that I did not want to be the consort of a legend. But by the laws of our people, I could only divorce you by the kal-if-fee. There was also Stonn, who wanted very much to be my consort, and I wanted him. If your Captain were victor, he would not want me, and so I would have Stonn. If you were victor you would free me because I had dared to challenge, and again I would have Stonn. But if you did not free me, it would be the same. For you would be gone, and I would have your name and your property, and Stonn would still be there.
SPOCK: Logical. Flawlessly logical.
T’PRING: I am honoured.
SPOCK: Stonn. She is yours. After a time, you may find that having is not so pleasing a thing after all as wanting. It is not logical, but it is often true. Spock here. Stand by to beam up. Live long, T’Pau, and prosper.
Calling out the single most important line:
T’PRING: Stonn wanted me, I wanted him.
Want is emotional. Her essential spiel is two arguments:
- I don’t want to be known as your wife
- Even if you win, you’d turn me loose, and I could find another.
There is a huge subtext in that episode… she’s speciesist. She wants pure Vulcan, not to raise quarter-human halfbreeds.
Likewise, in Journey to Babel, Sarek clearly is holding a grudge against Spock.
We see in TAS Yesteryear that, at least for the youth, there is overt racism happening on Vulcan. Were it not present in Vulcan in general, it would likely not have been tolerated in school.
BOY: Earther! Barbarian! Emotional Earther! You’re a Terran, Spock. You could never be a true Vulcan.
Y SPOCK: That is not true. My father
BOY 2: Your father brought shame to Vulcan. He married a human.
(Young Spock lunges at him, but they dodge him easily)
BOY: You haven’t even mastered a simple Vulcan neck pinch yet, Earther.
SAREK: My apologies, visitor. I regret you were witness to that unfortunate display of emotion on the part of my son.
Vulcans are shown to be lying about their pure logic civilization even in the initial two series. There is also a bit that’s really interesting - T’Pau refers to the Ponn Far
T’PAU: What they are about to see comes down from the time of the beginning, without change. This is the Vulcan heart. This is the Vulcan soul. This is our way. Kah-if-farr.
And let’s not forget that Vulcan logic dominance is under 5000 years. (All Our Yesterdays)
SPOCK: This is impossible. Impossible. I am a Vulcan.
MCCOY: The Vulcan you knew won’t exist for another five thousand years. Think, man. What’s happening on your planet right now, this very moment?
SPOCK: My ancestors are barbarians. Warlike barbarians.
MCCOY: Who nearly killed themselves off with their own passions. Spock, you’re reverting into your ancestors five thousand years before you were born!
SPOCK: I’ve lost myself. I do not know who I am. Can we go back?
Enterprise Era being a time of (well concealed) civil war on Vulcan, with one of the leaders being T’Pau, and T’Pau’s faction, a faction that is quasi-religious, being in charge a year or two later… A faction that carries around katra of venerable dead inside the heads of faction members…
Vulcan racism in TOS is shown; it’s nicely complimented by the ST III & IV elements, and then Enterprise gives us a civil war about religion… Not to mention Pajem…
A culture that is logic dominated and still religious either knows for certain that they have some benefit from religious praxis or is not as logical as they claim, and Vulcan in Ent can be shown to be both.
Contrasting this to the SFU version… it’s not really that much different culturally… The psionics masters also occasionally serve in the SFU Star Fleet, and they’re as smugly arrogant and condescending as what we see in later Trek… and especially Enterprise. Really, the only big difference is the tech disparity. Hmm… let’s check module Y1.
Early Years Vulcans do have better phasers (mobile Type 1’s), speed 24
Fed ships have speed 24 and type 2’s (which are weaker)
Rigellians are speed 24 and type 2’s
Alpha-Centaurans are Speed 16 and type 2’s,
Andorians are Speed 16 and type 2’s.
So, even in the SFU, the early years the Vulcans are tech superior to the rest of the feds, and their engine tech was usable on new construction, but, per Y1, other federation members couldn’t maintain the Phaser 1’s.
