I have a problem with moral outrage.
On the one hand, I often believe in the causes people are outraged about. On the other, I get so sick of the way they treat the causes as God's own truth. Let's pick an example cause: people being angry because they want a higher minimum wage.
I think the best salespeople truly believe in what they're selling. So it's a good thing that people really believe that there should be a higher minimum wage. On the other hand, the argument that a higher minimum wage would lead to less jobs has its merits too.
