BRYAN CAPLAN: Crusades and You.

Every five years or so, the United States has a major societal-wide crusade. Sometimes there’s a shocking event. Other times, there’s an ongoing evil. Either way, all Americans are supposed to join forces and take decisive action to win the crusade. And even if you can’t personally do anything, you’re supposed to get very angry.

You’re supposed to be very angry about the problem.

You’re supposed to be very angry about anyone who stands between us and victory.

You’re supposed to angrily support our crusaders.

And you’re supposed to be very angry about people who aren’t very angry.

5 years old, but still true. The bit about “effective altruism” hasn’t aged well though.
