I think we're more broadly running up against the dual nature of Star Trek. Its macro politics are unabashedly progressive -- pro-equal rights, pro-racial equality, pro-peace, anti-nationalist, anti-capitalist. But its micro politics are more conservative -- women are often depicted in sexualizing manner and as being emotionally weaker than men, and the whole thing is, to be a bit reductive, about space cops doing space colonialism in a space paramilitary. That's part of why Star Trek has broad appeal -- it's got the "We've overcome inequality and greed" stuff, but those speeches are delivered by guys in uniform who belong to an intensely hierarchical paramilitary organization, so it ends up appealing to both progressives and conservatives.
