Let me help you out here...
In your estimation what percentage of Americans know or care which acronym is used?
My guess is no more than 15 % at most...
So when I use the term ISIL, people will ask or try to correct me.
Using the preferred language of the enemy does little to inform your allies, and only aids and abets those we're fighting.
How exactly does using the term ISIL aids and abets the enemy?
Maybe your logic and intuitive thinking skills can explain?
So by you logo calling the "dirty japs" Japanese or"krauts" Germans during WWII we somehow aided them ?
Let me save you the trouble. No thanks.
