Progressives' Truck with Trek

Matt Yglesias has written a fine essay on the many incarnations of Star Trek, including a celebratory discussion of its implict (or should that be blatantly explicit?) progressive ideology, with a concluding plea for a new series.

I agree with Yglesias' interpretation of Trek ideology, though I do not join in fist-pumping such a utopian statism. Also, I could do without another series. Yet the importance/impact of the franchise is undeniable.
