Racism is an Inferiority Complex
The moment you think your value depends on putting someone else down. The moment you need to say you are superior to someone else to feel good about yourself, you definitely have a self-esteem problem.
The moment you feel that excluding some people will help you climb faster the social ladder, then you have problem with your total value in the human race.
The moment you need to put into place an international caste system to guaranty you stay on the top, it means you live with a strong fear about how valuable you are.
Racism is an inferiority complex.
Next time you face someone with racist idea or posture, pity him or simply ask him “Do you feel so inferior that you have to hate to exist?”
The day racism will be added to the dictionary of mental disorder, the world will be a much better place to live for all.
