Not a defect.
This morning I was able to put words to this. A difference in personality is not a defect in the other person. So many times, I see people looking down on other people because of a difference in character. It's called that most extraordinary of things, being human.
Let's extend that thought. • A difference in income level is not a personal defect.
• A difference in education level is not a personal defect.
• A difference in job position is not a personal defect.
•A difference in upbringing is not a personal defect.
•A difference in race is not a personal defect.
Another of the most human of things is to use those and other differences to elevate oneself to a level of self-importance over others. Perhaps, just perhaps the defect lies in self-importance.
