Well, let's be fair here: Spock was a racist and a hypocrite in TOS' TV series; he went on about all of humanity's failings and flaws like they were the worst bastards in space despite constantly encountering beings who were worse, and he kept forgetting that the Vulcans were far worse than humanity EVER was in their past. It wasn't until TMP that he realized that his general attitude towards things was wrong.
Physical comfort levels could have something to do with it. Andorians come from an ice world and Vulcans come from a desert climate. Adjusting common areas of the ship to accommodate both extremes would be nearly impossible.
I know!!! People cheered in the theater when he did that, because it was so clear that even though he didn't say it, what he was really saying was, "FUCK OFF."
To be fair, the Vulcans have always been portrayed as arrogant and smug in the belief of their own superiority. Even Spock was quick to point out humanity's failings and conveniently forgot about the bloody past of Vulcan. And don't even get me started on T'Pring! And what of Sarek, who stopped talking to his son for years because he didn't follow Vulcan tradition?
We are Judging Solok by human values. No wonder Vulcans look at us inferior Hew-mons with such distaste. Are we any better to judge them?
Humans never pretended to be totally logical beings who act without emotion. Vulcans constantly do. That alone holds them to a higher standard. Arrogance, smugness, claims of racial superiority...a logical species should not have those traits. Because they are inherently emotional.
Such an assumption is--for lack of a better word--illogical. See, having a "reasoned tone" hardly corresponds with "academically beating you up". It often means mere clever demagoguery, complete with projecting the attitude that "you're an idiot if you don't agree." In a word, "smugness". That's the attitude Solok expressed--the facts of his argument were of no consequence, so long as he said the audacious things he did (to the effect that Vulcans are, in effect, a Master Race) with a tone of, "and if you disagree with me, than you, sir, are decidedly lacking in logical reasoning."
Well, Surak would seem to think we have a point...as his interaction with Archer would seem to indicate.
