I was recently at a dinner party in mixed company. The political views of my fellow diners ranged across the spectrum from archconservative to radically liberal. I prefer the sort of arrangement. I’m a bit of a contrarian and I find nothing more tedious than agreement. This is particularly so when, as in this case, everyone at the table is intelligent and articulate.

Because we were a politically minded group, the topics focused mostly on current events, including Ukraine, the Obamacare rollout, and the latest Supreme Court decision on affirmative action. Eventually conversation turned toward the recently failed peace talks between Israel and the Palestinian Authority and, inevitably, to a discussion of settlements and the Israeli-Palestinian dispute generally.
