Spudbob: What Makes A Patriot?

Spudbob: “@Linda: I struggle with the concept that waving a flag makes one a patriot and a good American.” So … I have a sincere question for you. In specific terms what, to you, defines someone as being a patriotic American? P.S. No snark intended, I am really looking for workable definitions here

Question: So, in you estimation, what makes a person an American patriot?
