I think you miss the point of Star Trek, it, even more than most SF, isn't "really" about the future fictional or otherwise -- it is using the tropes of SF to make commentary on our society through analogy. That being said, I'm not sure the OP recognizes that Vulcans aren't entirely presented positively on the show -- they are generally viewed as missing part of life with their lack of emotions.

Too many words.

It's cool and fiction is how we stress-test ideas before they become policy.
