As I mentioned below, the “What would ISIS not want us to do?” is not a good heuristic, because by asking it you implicitly accept their world view.
I think part of the problem here is that it is difficult to discern how rational ISIS is as an organization. It is some combination of militia group; millennialist cult; and breakaway state. (It’s interesting that it has changed its name a couple times.) As best I can tell, the overall game plan of ISIS is—generally speaking—to follow in the footsteps of the most fundamental religious doctrine it can, and have faith that this will result in their eventual success. Under such circumstances, I don’t think it’s very useful to “avoid playing into ISIS’s hands.”
This may be a more useful consideration if the enemy was some kind of James Bond super-villain who was carefully scheming at every stage. Even then, you never know if the other fellow really wants something or if he is only pretending to as some kind of ruse or feint.
:shrug: Then you should have made that clear when you responded to my point, i.e. that you would respond to a different version of the article than the one I was responding to.
And you should have also applied the same principle of charity to my point and made it clear that you were changing the subject.
