Us vs. Them

In my previous post, I talked about the value of stories where people worked together toward a common goal. Unfortunately, all too often, these stories end up as "us vs. them". 

When you have nations battling nations, rebels fighting the government, even humans repelling aliens, the message is that we aren't all equal. It says that some people are fine to work with, but only because we are trying to defeat those who are different from us. It may promote teamwork, but not unity.
