I don't know, I actually like the whole flawed idea of vulcan logic. Throughout the different shows we come to understand that 'vulcan logic' isn't some weird alien "their brains work differently" thing. They used to be violent and emotional, and they came up with a social system that helped solve that, and ushered in an age if peace and progress.

But "logic" isn't a meaningful method to live a life, it's a very specific tool for certain types of problems. Even our primitive earth philopshers have identified many problems with thinking that we could live life purely logically, as Hume puts it "Reason Is and Ought Only to Be the Slave of the Passions”.

So we're not seeing a bunch of transcendent android minds, we're seeing the equivalent of a bunch of recovering alcoholics clinging desperately to a worldview that they cannot question, but that is itself "illogical". So their disdain for other races is partly a consequence of their general directness and not holding back criticism, but also an anxious defence mechanism of people who know that even their indoctrinating school system and constant peer pressure might not be enough if Vulcans feel like it's okay to like humans or whomever, because that's only one step away from "well, if they're doing okay why can't I fall in love and cry and laugh!" and that way lies bloody civil war and a return to barbarism.
