The article makes some good points. The conservatives, as usual, avoid them and explode in yet another victimhood tantrum. That's right, the phantom liberal bogeymen are coming to take your silly flags away. Better hunker down in the basement bunker.
There are no POWs. No other nation pretends to be a special victim because they had MIAs in a war, and it's time that large segments of the USA stopped whining about it. It's just embarrassing.
I do disagree with the Newsweek article that the flag is currently racist. While anti-Vietnamese bigotry was the origin of it, it's no longer used that way. It's used more often like flag pins. That is, as a bullying technique. Hyper-nationalists want to force conformity. Display all the right PC symbols, or they'll call you unpatriotic.
Fortunately, it's becoming a non-issue. I haven't seen one of the silly flags for a while, not even as a bumper sticker. As those who still obsess over an MIA issue from 40+ years ago die off, the flags disappear.
