Isn't revising your positions when you get more information or change your morals a good thing? I hate the villainization of changing your views. It's such a childish understanding of the world where that's a bad thing. It's probably part of why our society is so divided now. We've used "flip-flopping" as an insult, so anyone who ever admits they did something wrong or changed their opinion must be a bad person. In reality the opposite is true. Admitting fault and growing as a person is a virtue that should be rewarded.
