<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, in the United States, we have “us” and “them” based on our political affiliations. The concept of “us” and “them” is not universal, however, and there are many different cultures that have their own unique ways of classifying people into “us” and “them”.
