Here are some quick, belated thoughts on why the Star Trek universe (which should be celebrated) is appropriately analogous to Columbus Day (which should not be celebrated):

One of Star Trek’s main purposes is to revise the tenets and practices of imperialism and colonialism, to promote the idea that humans can perhaps explore the world (the universe) around them without actually conquering it.

Humans like to say things like ‘the human spirit’. They like to think it means something, that it’s what’s special about them. That it separates them from other animals. There’s that new movie out, 127 Hours, starring James Fracno, about that guy, Aron Ralston, who got his arm caught under a big rock when he fell into a canyon, and he had to cut the arm off with a really dull multi-purpose knife. The movie’s about, like, ‘the human spirit’.
