Angie Schultz calls my attention to James Lileks on Star Trek. I have to disagree with him on this point:
[The Borg] were joyless cyborgs intent on crushing all cultural differences. They were the Republicans!
The Borg are utterly egalitarian, and utterly conformist in the name of diversity (“We will add your uniqueness to our own”); seems to me there’s another gang of thieves who fit the metaphor slightly better.
