The Vulcans were flawed long before Enterprise. Heck, the first Vulcan we ever saw besides Spock was T'Pring in "Amok Time," who plotted to get Spock and/or Kirk killed just so she could marry someone else. And then there was Sarek, who was estranged from his own son for eighteen years because they disagreed over his choice of career, and who also concealed a serious heart condition from his own wife. Sorry, that's pride and stubbornness, not logic.
And need I mention Valeris?
And T'Pau. Who openly mocked Spock and Humans.
I never did understand the claims that Enterprise got Vulcans "wrong".
