This media storm is even more stupid than the one based on a video purportedly showing Marines urinating on dead terrorists. The Marines in question were likely born in the ‘80s and ‘90s, and World War II and its symbols are not known among this generation. (To be fair, the nitwits wearing Che Guevara T-shirts are also ignorant of history.)
We know (or ought to know) what the mainstream media's interest is in this story: it is to promote a false narrative - America is racist and bigoted, and our soldiers are heartless killers who are creating terrorists rather than merely fighting against them.
The real story, I think, is that too many young Americans are ignorant of the facts and symbols of their own nation's history, thanks to a corrupt educational system and a news media that promotes an ideological agenda through the use of selective facts and intentionally slanted language.
