T'Pol was pretty bigoted, as I recall. As far as Spock and Tuvok, I think they hid it a little better, but they were both still arrogant and abrasive, showing a lack of willingness to accommodate the social graces of others.
At least...Spock was in his earlier years. I think it was pretty clear by the movie era that he'd mellowed. And in Trek XI, his behavior actually looked for the first time like a clear cross between human and Vulcan behavior, like he'd fully accepted both sides of him.
