So while Tacoma the Klingon is delivering one of his oh so delightful Klingon language monologues, one of them he runs through the founding races of the Federation saying "Humans, Vulcans, Tellarites, and filthy Andorians." Why are Andorians the ones he singles out as "filthy"? After all, the Tellarites are the ones who literally are pigs wallowing in mud, wouldn't that be the very definition of filth? And given Andorians are themselves a warrior culture, shouldn't they be one Federation race the Klingons would actually respect?
To humans, Tellarites would be seen as such. It's just another example of perceptual differences from different species. It's disturbing to watch on one level yet on another it's not what I'd expect.
Maybe he is prejudiced against their four-person marriage structures.
