[Star Trek] Why are Vulcans such assholes to different cultures?

It seems to me that being antagonistic to other species would only cause hostilities and therefor be illogical.  Particularly I'm watching Enterprise and they seem to almost go out of their way to be dicks.

The important thing to realize is that Vulcans aren't nearly as good as humans are at reading what other humans are thinking.

Humans are one of the most highly evolved species for creating working theory-of-mind of our own species.  Autistics aside, we're near telepathic with our ability to anticipate the actions of someone else.  That's why games with hidden information like poker are so popular with humans, whereas Vulcans gravitate more towards full knowledge games like chess.

Vulcans create mental models of the humans they deal with, and that model assumes we are perfectly logical.  When they are "antagonistic" what they're actually doing is saying "we find you inferior."  Vulcans do not consider such a thing offensive to say, they have less emphasis on saving face.

Where Vulcans fail is that they assume we, too, think logically.  They operate from failed premises.  When we fail to respond, they double down by showcasing their superiority to make the situation clear.  They imagine our non-compliance to be because we didn't get the power disparity.

Vulcans are smart, but their psychology isn't the same as ours is.  In many ways they're actually quite similar to Klingons -- they are extremely direct and honest.  They say what they mean and mean what they say, and if they have feelings so sufficient that they want someone else to truly get them, they mind-meld.
