Was joking earlier today, in the context of protecting ourselves from imaginary threats, about planning for zombie attacks.  And then came across this review of a zombie-centric comic series that raised a rather real question:

What makes The Walking Dead so compelling to me is the way it asks you to decide, over and over again, do you bug-out (get away with your loved ones) or bug-in (help your neighbors and let them help you), or both? I’ve always hoped that I’d be a bug-in person, that in a disaster I’d work for the mutual aid of everyone. But bugging in works best if the rest of the world does it with you — a few selfish buggers-out shatter the social bonds that make it possible for the most people to survive a terminal prisoner’s dilemma. But even for us bug-in types, Kirkman wants us to ask ourselves, how far will you go? Who gets to come inside the shelter with you, and who gets left outside to die?

This isn’t a Choose Your Own Adventure exercise.  It’s much more:

This is the kind of ethical question that underpins our responses to everything from humanitarian crises like the one in Haiti to the health-care debate to immigration and refugee policy. It’s at the core of racism and sexism, at the core of xenophobia and discrimination. In its most extreme form, it can give rise to horrors like the American eugenics movement or Naziism, but who among us doesn’t have a secret kernel of it lurking in our breast?
