The “Us vs. Them” mentality is also called the “in-group bias”, in which you tend to align with other members of a perceived group (with little to no logical reason, it can be as simple as belts vs. suspenders). Like many other fallacies or biases, it is a built-in feature of our caveman-brains that no longer benefits us. When used in propaganda, it is often paired with the “strawman fallacy” to build the perception of an enemy that is barely even human.
You can learn to recognize these biases in yourself and in others - This is called critical thinking. I recommend the podcast “You Are Not So Smart” to everyone to get more insight on this subject.
