What the hell are we supposed to tell the kids?
I'm not sure I follow.
Surely the only way the orange jumpsuits could win more recruits is by reminding them of Guantanamo? So if it is a recruiting tool, it is one that uses the prospect of revenge as its main facet. It's undeniable that they are a reference to Guantanamo, and therefore it seems clear that ISIS view their actions as some kind of response to what they consider Western aggression.
Again, you say that the jumpsuits are designed to appeal to those "who aren't just upset about the suffering of muslims throughout the world but are drawn to and attracted to violence," but I don't see how you can separate the two motives. Surely those Muslims who are attracted to this kind of violence will be so attracted because they see it as a means to revenge.
And finally, there is no other plausible motive. These executions don't bring any tactical or propaganda benefit. The only benefit they can bring is the gratification that springs from vengeance.
Leaving aside the question of whether this lust for revenge is justified for now, can we at least agree that this is what motivates these atrocities?
The message is 'you will burn in hell' for opposing us, simple as that. Promised before in words and now made visual.
