American here, and I was a little boy scout like 30 years ago so I actually learned some of the rules of the US flag code.
Ever since then I have constantly noticed many of the people who most need to display their patriotism also being ignorant of the official rules for showing respect to their favorite flag.
And to be clear, I don't care about the rules surrounding the flag. It's just amusing and/or sad to see how superficial people can be and how little effort they put into learning about anything, much less something that is core to their identity. See also: rules in the bible.
