I assume when you speak of "the uneducated", you are standing in front of a mirror. This is a matter of principle, not schooling. If the flag is not a danger to anyone, or in any way restricts how an adjacent property owner can use and enjoy his property, the business should be able to fly any size American flag that it wants to. I assume that you are one those who look toward elected officials on all levels of government for guidance and to dictate how you must live your life. Apparently there are a few left that desire to make their own decisions and feel it necessary to stand up for others like the store owner who feel likewise. This is what America is all about. Perhaps you would feel more at home in Communist China.
