When people change their minds over an important or heated topic, we immediately label them as wishy-washy. Unsure of their own beliefs. Yet we shout and try to convince people to do just that, change their minds.
Not only do we count a change in belief against someone, but we judge present actions in light of their past. If we hold to the adage, “he who is without sin cast the first stone,” perhaps we should listen to others in the present without context from the past.
