I guess we all have our own insecurities; for one person it might be her body image and for another her financial issues and yet for another her lack of formal education. It is interesting that we perceive of insecurity as a feminine attribute and yet it seems to be a universal characteristic of all human beings: I did not get enough love when I was a child, I was never good with math, my nose was big, my body was fat, my family was poor, my friends were ignorant, and you name it. so, one doesn't need to mention that if our peculiar case was in fact very common then it could not qualify as an insecurity. One of the causes of our discriminatory behavior is that we are “comparing creatures”. We learn that certain attributes are good (either through our nature or via nurture) and then we seek those attributes in ourselves and when we don't quite find it we get disappointed. One way of dealing with them is to try to improve upon ourselves. That comes with a great deal of suffering and energy expenditure and life is finite after all. Or alternatively, we can try to make peace with our shortcomings. We also have a sense of justice that tells us to what extent a given person (including ourselves) deserves certain privileges. So, we construct a system of proportions and correspondences and expect certain actions yield certain consequences and certain guys marry certain girls. Then, for the rest of our lives we live within the confines of these philosophical construct and practice our judgments. Occasionally, we see or hear cases that deviate from our expectations and it surprises us, but then we go on. What is wrong with this system?
