The interesting thing is that everyone except white cis wealthy men are other. And even some men within that group think of themselves as being "othered" by the "other;" that they are losing control over their world - the world. And I have always felt that creating boxes is a way for those who embody the Dominant Narrative to know how to interact with others. If you are a black, poor single mother - well there are certain expectations placed on your behavior and whether you live those expectations or not I am going to treat you as though you do. It is, yet, another way to halt truly interacting with other people. Those boxes is what facilitates the growth of nationalism.
