In some aspects of our culture, shame still exists to great effect. For example, drunk driving is a behavior that never gets a pardon. Words never spoken: "We shouldn't judge Joe for his DUI, for if we were in his shoes, we may have done the same."
The drunk driver may deserve all sorts of considerations: They struggled with alcoholism, their judgment was impaired at the time, they needed to go to work in the morning, they couldn't afford an Uber, their designated driver didn't show, they didn't speak English well enough to coordinate another ride home. In function, no excuses are allowed. As a culture, we believe that no matter your situation, you must always make plans to avoid driving drunk.
What if this same type of intense shame existed towards other behaviors we wished to not see? To name one: What if we intensely shamed parents who let their young children become obese? Instead of blaming food deserts, lack of nutritional knowledge, lack of time to prepare meals, and so on, what if the blame went directly to the parents who are letting their elementary age children graze on a party sized bag of Doritos?
