Yeah, but with the Vulcans it actually kind of makes sense that they're racist as hell because they're also really useful for stuff. They have great computers, lots of start charts, good technology, and they're relatively smart as humanoids go. They contribute to the federation behind their wall of smug superiority and nobody bothers them for it.The Vulcans are as bad or worse, Earth occupied by a fanatical government at the time for 90 years, abandoned by them in the Romula War, and yet a founding member of the Federation.
Klingons are just... dicks.
