That's hyperbole and unrelated to this entire thread. It's over-the-top rhetoric like that that makes me shake my head in dismay. Whoever suggested that? Whoever did that?
I stand with OldSmaj.
Those restrictions are part of the same "flag code" that states that no flag should fy above the US flag. At least as I learned it in scouts -- I've heard that they dropped the rule about leaving the flag flying in the rain, because most modern flags are made of artificial fibers that don't mildew.
