I know it feels like too much, you just feel like being outraged sometimes, don't you? But trust me, we gotta try it for a few centuries and see how it works out. You'll be surprised by our progress.
There are times when outrage is entirely the right emotion to feel. The problem is when we live in a permanent state of outrage, or when we pretend to be outraged to get what we want.
If we "ban outrage", then somebody needs to be the outrage police and decide when it's acceptable.
