“Research tells us that we judge people in areas where we're vulnerable to shame, especially picking folks who are doing worse than we're doing. If I feel good about my parenting, I have no interest in judging other people's choices. If I feel good about my body, I don't go around making fun of other people's weight or appearance. We're hard on each other because we're using each other as a launching pad out of our own perceived shaming deficiency.”
