A friend sent me a long but very thorough article on the effects of changing social norms. It was interesting because it started with this, “Unlike most libertarians, I don’t have an opinion on gay marriage, and I’m not going to have an opinion no matter how much you bait me.” But, she went on to give various reasons why this decision goes much further than whether or not we’re discriminating. She discusses the changes to welfare, social security, and divorce law. I found it very helpful to see through the flawed arguments on both sides. Towards the end she says, “My only request is that people try to be a leeetle more humble about their ability to imagine the subtle results of big policy changes.” Humble? What’s that?
