How do you choose between the Resistance and Enlightenment?
Sure seems like fearing the aliens would be a very Tea Party-ish thing to do, which makes me really surprised BRTD picked it. Do you just ignore logic like that and join whichever team your friends are on?
All the people I know IRL who have caught up in this thing are Enlightened, and their reasoning is pretty much this. (Or, more accurately, the first adopters reasoned this and then everyone else signed up on the side their friends were on.)
There was also an analogy to Tokugawa/Black Ships/"Resistance is basically like Juche" in there somewhere.
