Is being judgmental necessary?
Not at all. Ever. What is necessary is evaluation. But the subject of your evaluation is important. It is necessary to evaluate from a personal survival and personal comfort perspective. All else is futile. Your “judgment” of anything does not change anything. When observing things outside of what directly affects or will affect you, do not judge, merely observe and act in a way that protects you and your loved ones. When presented with something that will affect you, evaluate from the standpoint if whether it is beneficial or not. Act on that evaluation.
