Pretty much everyone over about 40 who rides a motorcycle wears this as a sticker or patch.
This flag is one of the most Weird American Things I can think of

It's the POW/MIA flag. It's flown over the White House, alongside the American flag, since the 80s (off and on). As of 2019 it's mandatory to fly it over federal government buildings; it flies over state government buildings in many places as well. It seems like a neutral sign of military support, so it's easy to pass over it without asking "wait, are there any American POWs"
Then if you look it up it's the symbol of a Vietnam-era conspiracy theory debunked in 1993. This is the flag for the 70s/80s version of Pizzagate, and it flies over the US Capitol building and White House every single day
