Appropriate? I would tell those people to get a life, it's just a flag. This is not a criticism to anyone in particular on this thread, just a general rambling about this sort of "happenings". I understand some people have a deep sentiment of patriotism instilled into them, but this is ridiculous.
I don't see concern as being ridiculous IF it is against the code that outlines proper procedures for displaying the flag. I still don't know for sure whether it is inappropriate however.
