“… then it is a lie.”
Living out of this mentality makes us fragile and reactionary.
The ability to consider the truth of another’s experience, even momentarily and provisionally, is fundamental to an empathic life in community.
This is not a permissive acceptance of everything thought or felt. (So not: “Everything is true everywhere!”) It is an empathic habit that leads to our ability to see the complexity of our world so that we can prudently love within it.
