What are the causes of U.S. patriotism?

Question

what are the social factors?

Answer 1

People in different groups feel an intense sense of pride of their community, and their "people". This in turn leads to a feeling of pride and love for their system, and this view seems to make them believe their government and leaders as incapeable of flaw, or very understate mistakes. This view make them feeling invincible, or a need to protect this system. I think that is might be the process of how patriots develop. I hope this explained it.

Answer 2
