Flags: they're not wrong.
"Every American flag is a warning sign" the message said.
Have you noticed how many stars-n-stripes there are on Youtube these days? It's like every content maker needs to show you how much of a patriot they are by displaying their country's flag - on the wall behind them, on the t-shirt or jacket they wear, flying from the pole out front or the pick-'em-up truck they coal roll. They even display them incorrectly (there are actual laws about that in the USA, but hey they're not big on laws anymore) and think that makes them even more so.
You know what kind of countries have flag-waving obsessed citizens? Places like:
North Korea
Communist China
Soviet Russia
Fascist Italy
Nazi Germany
And any two-bit banana 'republic' dictatorship you care to name.
Yep, them 'Muricans sure am true patriotical people!
