For the most part, Europeans don’t display their flags unless there’s some
really important event...like an international soccer match.
And AFAIK, they DEFINITELY don’t have the same kind of rules regarding display, reverence, or disposal of their flags as we do. I’ve seen Europeans do a lot of things with their flags that Americans would consider disrespectful.
OTOH, some of our “patriots” will use our flag in ways that Europeans find
baffling for something so apparently beloved, especially on clothing. I mean, why would you wear a patch depicting your revered flag on the ass of your shorts? As a thong bikini?
Or, as you point out, in poor condition or dragging it in the dirt.
Me? I was in scouting, and grew up as an Army Brat. We don’t male those mistakes.
A lot of our neighbors pay to have largish flags on poles placed on their lawns for the big patriotic holidays
...displaying them un-illuminated during inclement weather and at night.
On those same holidays, some businesses festoon streets with small flags- some with their business cards in the little sticks- not only committing the same error, but also not monitoring if/when they fall over and recovering them.
