My bad, I should have been more clear. I meant canonizing the idea that Vulcans of the pre-TOS era were not as 'perfect' as they later seemed be.
When were they ever perfect?
T'Pring, who cheated on Spock and lt him fight to the death with his own captain so she could keep bonking Stonn? T'Pau, who treated humans with disdain? Sarek, who refused to talk to Spock for 18 years for choosing the wrong career path? Young Spock's Vulcan tormentors in "Yesteryear" (TAS)? The Vulcan Masters who coldly pronounced Spock a failure in his kolinahr? DS9's serial killer? The Vulcan baseball team in "Take Me Out to the Holosuite"?
