Self-Control

Sure, you can negatively judge others based on physical aspects of their appearance which they cannot control. For example, I've observed so many people criticize others (including me) because of the shape and/or size of their facial features. However, each time this happens I take comfort in the knowledge that (without exorbitantly expensive elective/cosmetic/surgical procedures) these circumstances are out of my control. Alternatively, the instigators of such distasteful insults typically (and ironically) omit the reality that they can control their weight, their cleanliness, their attitude, their language, their behavior, their confidence/insecurity, etc.
