Charles Pierce blames fragmented politics for fomenting terrorism at home:
We are political animals. It is a truth as old as Aristotle, who attributed our political nature to the fact that, unlike any of the other animals that travel in herds, we are able to speak. We can ignore the politics central to all our various interactions, or we can pretend that actions, good and bad, are apolitical, but politics is there, binding us up, regardless of how fervently we deny it, which we do, and take refuge then in fragmentation rather than confront what we may have in common with other people — strange people, crazy people, violent people — who share with us the politics of our common humanity.
David Neiwert argues that right-wing domestic terrorism is our big blind spot.
