We *do* have another tool for social change: guilt.

Based on her research, Brene Brown separates shame and guilt as guilt says you did something bad, and shame says you *are* bad. She further identifies that guilt can be a healthy motivator while "shame corrodes the very part of us that believes we are capable of change" (aka unhealthy).

I feel like you’ve created a false dilemma by stating that either we use shame or we attempt to only argue logically. Guilt can be just as powerful a motivator, yet does not have the emotionally scarring nature of shame.
