Judgement is natural but the way we perceive and act upon the information that we get from judgment is what really matters.
I have found that it is impossible for people to avoid making judgments. It is NECESSARY to make judgements. This is how we understand people and who they are, so that we are able to determine if they are a person that would be a positive impact to keep in your life. So the difference between “judgmental” and “nonjudgmental” is how we decipher and act on our judgements about another person. Even if we disagree with an aspect of a person’s character, a “nonjudgmental” person will accept them for being this way but simply conclude that a person isn’t someone that we want to spend our time with, nor do we want to acquire these unfavorable characteristics.
