<human>:  Where does the concept of ‘us’ and ‘them’ come from?
<bot>: The concept of “us” and “them” is a social construct. It is a way of categorizing other people. For example, you might think of a group of people as “us” or “them,” depending on whether they are like you or not. It is also a way of making sense of the world. For example, you might think that the world is made up of two groups: “us” and “them.” This is a very simple example, but it illustrates the point that people can use “us” and “them” to make sense of the world.
