Passing comment or opinion on the actions, appearance or words of another person creates distance. In your mind, it puts you above them. You feel you have a right to be heard. It creates disdain and superiority.
On a long enough timeframe, separation leads to loneliness. Loneliness leads to suffering. Sooner or later, someone will need to fit a very specific set of criteria in order for you to accept them as an equal. Maybe there will be no one left who fits your standards.
