Sorry, shootinstudent, you can't throw water on this one.
They're selling it as PLO gear. PLO is a terrorist organization. It's being sold as a symbol of a terrorist organization. Therefore, I think everyone is free to make fun of it, spit at it, and talk about how they'd use it in a manner that reflects their feeling towards that terrorist organization.
Because that group is actually performing terrorist acts against our ally they're a legitimately labeled enemy. And when someone is your enemy, you can make fun of them. They did it in WWII, for sure, and it helped morale. All sorts of unflattering spoofs about Hitler and Nazis, most often. Best way to de-fang an enemy is to laugh at them.
Deal.
