The easiest way to feel empowered is to claim identification with some sort of group (gender, nationality, religion, etc). It is the laudable characteristics of that group that you identify as your own characteristics, which are based on the way a gender, a nation, or a religion prefers to think about itself.
The easiest way for a group to build its sense of identity is through the rejection or the demeaning of that group’s “opposite.” In order for atheists to present themselves as rational and intelligent, they have to present the religious as superstitious and foolish. This is certainly easier and more effective than consistently being rational and intelligent. In order for America to think of itself as strong and important, it has to think of Europe as being weak and worthless. And in order for women to think of themselves as compassionate, they have to think of men as violent.
Part of this is simple projection. All the aspects of yourself that you are ashamed of or fear that you possess (weakness, anger, irrationality) can be easily forgotten if you assign those traits to someone you are not. If you strongly identify as one thing, your opposite can be not only a scapegoat, but a shit storehouse. Anything you’d like to distance yourself from can simply be stored in the identity of your opposite. “This group over here is ___________ [enter whatever disgusting thing you can’t bear to see inside of yourself]. I belong to the group that is the opposite of this, and so therefore I possess the opposite qualities.”It is always easier to find your sense of value by demeaning another’s value. It is easier to define yourself as “not that,” than to do an actual accounting of your own qualities.
Which is why the casual hatred of men as a gender is so disturbing. It is the same thing men have done to women for centuries. In order not to feel weak, they projected weakness onto us. In order not to feel emotional, they projected their emotions onto us. Now when women want not to feel foolish, they project foolishness onto men. When they want not to feel destructive, they project their destructiveness onto men.
