How much evil throughout history could have been avoided had people exercised their moral acuity with convictional courage and said to the powers that be, “No, I will not. This is wrong, and I don’t care if you fire me, shoot me, pass me over for promotion, or call my mother, I will not participate in this unsavory activity.” Wouldn’t world history be rewritten if just a few people had actually acted like individual free agents rather than mindless lemmings?
On a grander scale, when a society segregates itself, the consequences affect the economy, the emotions, and the ecology. That’s one reason why it’s easy for pro-lifers to eat factory-raised animals that disrespect everything sacred about creation. And that is why it’s easy for rabid environmentalists to hate chainsaws even though they snuggle into a mattress supported by a black walnut bedstead.
