I bought some cheap Chinese 2-way radios. The packaging has a big American flag and a “Designed in U.S.A.” claim, which I suspect is bullshit given the company involved. Also, there are two Bible verses referenced. This smacks of pandering to a particular slice of conservative Americans. All I want is cheap radios for skiing with my kids next winter, not a reminder of my country’s socio-political bullshit.
Black and gray flags are used by the US military on some uniforms. Civilians also sometimes display them as “no quarter” flags, meaning the person displaying the flag will show no mercy to any perceived enemies. For both of these reasons the right-wing nationalist crowd likes them.
