It's time we began to defend the right to be wrong. Throughout my life I've said an enormous amount of stupid and ill judged stuff. The reason I know that I've said a lot of stupid things is because I debated these ideas and they fell apart. Today, we are obsessed with the view that people ought to be permanently defined by something they said 10 years ago. It's madness, and it's dangerous. If we create a requirement that nobody ever say anything stupid then we eliminate ideas, debate and creativity. I do not believe people I disagree with are evil, I just think they're wrong.
